I know the answer, but it pisses people off.

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

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

    -6

    (-6)-7=-13
    19+(-6)=13
    X=/=-6

    The only answer I can think of is infinity.

    Yeah it’s not -6. Oops.

    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.

    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)

    x = ∞

    @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

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

    Ah, okey dokey. Sorry ’bout that.

    Although lim(x→∞){x-7} = lim(x→∞){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) – 7 = 19 + (12i)
    Multiply both sides by i + 1
    -12 + 5i – 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

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

    Howie Feltersnatch

    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.

    x-7=19+x
    (add 7 to both sides)
    x=26+x
    (subtract x from both sides)
    0 =/= 26
    False

    LichenFace
    Member

    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…

    multiplying i by -1 does not give you -1, it gives you –i. i squared gives you -1.

    @nyokki: you’re right. I fucked up there.
    It was worth the effort.

    x-7=19+x
    x-x=7+19

    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.

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

    asymon
    Member

    @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 🙁

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

    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,… Read more »

    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.
    I’m in grade 11, I learned this in class last year,and people with Univiersity degrees agree with me, even if people with English degrees don’t agree with my spelling.
