    Angry stupid me

    I know the answer to the equation however i cant seem to get the math to work out. Here is the equation.

    x-5/3 - x-4/3 = x-3/2 - (x-2)

    I assume,
    \frac{x-5}{3}-\frac{x-4}{3}=\frac{x-3}{2}-(x-2)
    The common denominator exists and is 6.
    Multiplication by six produces,
    2(x-5)-2(x-4)=3(x-3)-6(x-2)
    Open,
    2x-10-2x+8=3x-9-6x+12
    Combine,
    -2=-3x+3
    Subtract from both sides,
    -5=-3x
    Divide,
    x=5/3

    Yes. Thank you. Since it's the original answer I had I'm going to assume I'm right until the instructor says otherwise. Thanks again for your help!

    I presume,
    \frac{x-5}{2}-\frac{x-4}{3}=\frac{x-3}{2}-(x-2)
    The Commond Denominator exists and is 6.
    Multiplication upon the equation produces,
    3(x-5)-2(x-4)=3(x-3)-6(x-2)
    Thus,
    3x-15-2x+8=3x-9-6x+12
    Combine,
    x-7=-3x+3
    Add 7,
    x=-3x+10
    Add 3x,
    4x=10
    Divide by 4,
    x=10/4=5/2=2.5

    A suggestion: Next time post the correction in the original thread. That way eveyone can see where the mistake was made and be able to follow it without having to jump threads.
