No no the point of this is that you photoshop the equation out and then add your own text, for example, ‘Is Moot a fag?’ Then it makes it look like the answer is obvious.

You generally don’t want to divide by x, if it’s not already a denominator, then you also have to show separately that x=/=0 (which also is true). You just subtract 2x from both sides.
2x = x+x
2x = 2x
-2x -2x
0=0 (true for all values of x)

I was able to figure it out, despite the fact that the last time I studied calculus was in high school.

Although lim(xÃ¢â€ â€™Ã¢Ë†Å¾){x-7} = lim(xÃ¢â€ â€™Ã¢Ë†Å¾){19+x}, this still doesn’t make the original equality true. Just because lim a = lim b, this does not necessarily imply a = b.

There really isn’t an answer. I guess if you read Hoffstedter’s “Godel, Escher, Bach: An Eternal Golden Braid,” you could try to claim the answer is “mu.” But you’d still be wrong.

i = the square root of -1
The absolute difference between -7 and 19 is 12
Use 12i for X
(12i) Ã¢â‚¬â€œ 7 = 19 + (12i)
Multiply both sides by i + 1
-12 + 5i Ã¢â‚¬â€œ 7 = -12 + 31i + 19
5i -19 = 31i +7
5i = 31i +26
Multiply both sides by i
-5 = -31 +26i
26 = 26i
Multiply both sides by -1
-26 = -26
0 = 0
X = 12i

Actually, lichenface, when you come up with 0=0, that means that the problem is true no matter what you put in. If the problem is 6*x=(5+1)*x, x could be anything, you could say that x=bologna! and it would still come out equal

oh and when you multiply 26=26i by -1 you get -26=-26i.

the question is pointless, if you subtract -7 from both sides, the problem results in saying that

You people should drink more. You obviously have brain cells trying to commit suicide anyway.

LichenFace’s answer is obviously wrong. His first step implies that 12i = 26 + 12i, which isn’t true. Also, he errs claiming in 26 = 26i, that when you multiply both sides by -1 you get -26 = -26. Wrong. You get -26 = -26i, which is still not a true statement.

Again, there’s no trick here; there is no solution.

Paul_is_Drunk, I suspect that if people “get made” about the solution you proffer, it’s because you’re offering a wrong solution. Invoking i doesn’t help.

False

X = 1 to 31 at midnight any day in March of a non-leap year, next to the international date line.
For example if X = 1, that would be day 1 of March.
X-7 means 7 days prior to March 1 which would be February 22.
19+X means 19 days + 1 would be February 20.
That’s two days off, so you have leap across the international date line to adjust one day,
doing it at midnight just when the 20th becomes the 21st.
Solved using my very own thinking meat.

I had a prof in Real Analysis (advanced calc) that would purposely give us work we couldn’t do yet. After getting a 31 on a the 1st test worth 135, I was ready to drop the class. Then I saw the A in the corner and when I asked (also noticed that I had the 2nd highest score)him, he said “This is the test you should be able to complete at the end of this semester”. He wanted to see what we’d do. How many of us ran around in circles fooling w/ every algebra and proof trick we knew, and how many of us did nothing? He said I got an A because I attempted each problem, tried a few things and then even wrote (at the end of each problem) that I didn’t know how to proceed. So I didn’t try too much and didn’t quit at the beginning. Anyways, this thread is starting to look like the circus of my fellow students’ tests in that class.

(You added X to the left hand side, and subtracted X from the right hand side.)

Omg you dropouts.

x-7 = 19 + x
(tansfer numbers so that numerical values and variables are together.)
x – x = -7 +19
(x is found;however, cancels out)
(x is replaced by 0)
0 = -7 +19
0 = 12

.’. eq > or = WTF?

It’s impossible.
X must be given.

And btw, he was joking about being able to solve it.

the left and right sides are not equal. there is no solution

I was figuring that as well. 0 =/= 24

x = FAIL

-6

(-6)-7=-13

19+(-6)=13

X=/=-6

The only answer I can think of is infinity.

Yeah it’s not -6. Oops.

my mind is fucked!

there is no solution to the problem.

any x you pick will not make the equation true.

x – 7 = 19 + x

Subtract an x from both sides:

-7 = 19

This is FALSE, therefore there is no solution.

You sometimes may get a similar senario such as:

2x = x + x

2x = 2x

divide both sides by x:

2 = 2

since this is TRUE, it’s true for all values of x, so there are infinately many solutions.

Soo what anime is that?

No no the point of this is that you photoshop the equation out and then add your own text, for example, ‘Is Moot a fag?’ Then it makes it look like the answer is obvious.

KOBIASHI MARU!

You generally don’t want to divide by x, if it’s not already a denominator, then you also have to show separately that x=/=0 (which also is true). You just subtract 2x from both sides.

2x = x+x

2x = 2x

-2x -2x

0=0 (true for all values of x)

x = Ã¢Ë†Å¾

@...nyokki:

If you subtract 2x from both sides you get:

-x-7=19-x

Which is no help whatsoever because that simplifies to -7=19

Also, w0x copied his post from Yahoo! Answers.

@...Ben1605: Sorry I was referring to w0x’s 2nd example equation.

Ah, okey dokey. Sorry ’bout that.

Cyrstalkestral is on the right track.

Like I said, you won’t like the answer.

That being said though, there is an answer.

I was able to figure it out, despite the fact that the last time I studied calculus was in high school.

Although lim(xÃ¢â€ â€™Ã¢Ë†Å¾){x-7} = lim(xÃ¢â€ â€™Ã¢Ë†Å¾){19+x}, this still doesn’t make the original equality true. Just because lim a = lim b, this does not necessarily imply a = b.

There really isn’t an answer. I guess if you read Hoffstedter’s “Godel, Escher, Bach: An Eternal Golden Braid,” you could try to claim the answer is “mu.” But you’d still be wrong.

Think about square roots.

i = the square root of -1

The absolute difference between -7 and 19 is 12

Use 12i for X

(12i) Ã¢â‚¬â€œ 7 = 19 + (12i)

Multiply both sides by i + 1

-12 + 5i Ã¢â‚¬â€œ 7 = -12 + 31i + 19

5i -19 = 31i +7

5i = 31i +26

Multiply both sides by i

-5 = -31 +26i

26 = 26i

Multiply both sides by -1

-26 = -26

0 = 0

X = 12i

Actually, lichenface, when you come up with 0=0, that means that the problem is true no matter what you put in. If the problem is 6*x=(5+1)*x, x could be anything, you could say that x=bologna! and it would still come out equal

oh and when you multiply 26=26i by -1 you get -26=-26i.

the question is pointless, if you subtract -7 from both sides, the problem results in saying that

x=x+26

Damn!

LichenFace had my answer.

Though I have no idea where he got 0=0 from, though.

You people should drink more. You obviously have brain cells trying to commit suicide anyway.

LichenFace’s answer is obviously wrong. His first step implies that 12i = 26 + 12i, which isn’t true. Also, he errs claiming in 26 = 26i, that when you multiply both sides by -1 you get -26 = -26. Wrong. You get -26 = -26i, which is still not a true statement.

Paul_is_Drunk, I suspect that if people “get made” about the solution you proffer, it’s because you’re offering a wrong solution. Invoking i doesn’t help.

x-7=19+x

(add 7 to both sides)

x=26+x

(subtract x from both sides)

0 =/= 26

False

Let me put it so you understand

26 = 26i

divide by 26

1 = i

multiply by -1

-1 = -1

0 = 0 came from adding 26 to both sides or in this case adding 1

0=0 just means that the equation works and you can’t just make x anything as we have all tried.

so…

Paul_Is_Drunk = bologna

multiplying

iby -1 does not give you -1, it gives you –i.isquared gives you -1.@...nyokki: you’re right. I fucked up there.

It was worth the effort.

@Ben1605

Just thought I’d show you guys that there is no way to solve it, so I copied it. :3

x-7=19+x

x-x=7+19

=26!!!! WTF FAIL!

@LichenFace

My answer was 26 = 26i.

That’s the closest I’ve come. That’s why I said people would be pissed with the answer, because it’s not really an answer.

I can see where you got 0=0 from now, though.

Damn straight 26=26i isn’t an answer….because it’s wrong.

@Paul_Is_Drunk “My answer was 26 = 26i.”

You cannot write that, because it implies that 1=i, what is wrong.

Simply, this equation have no solution and we all must live with it 🙁

nerd war!

Reboot you have like three degrees in pure math. Can you please just post in this thread so this can god damn stop?

@...Caio: There is no solution. I have a degree in math also. Ok?

Yeah but you’re not commanding enough to make people stop posting about this.

@...Caio: Ah! Ok people, listen up. I HAVE 50 MILLION TRILLION BEZILLION DEGREES IN MATH! THERE IS NO SOLUTION TO THIS PROBLEM! I think.;)p
