    Algebra Simplification

    Hi All,
    [tex] y + 4 = \frac{x}{2} [\MATH] Solve for y.

    [tex] y = \frac{x}{2} - \frac{4}{1} [\MATH] = [tex] \frac{x - 4}{2} [\MATH]

    However the answer is [tex] y = \frac{x-8}{2} [\MATH]

    Where did I go wrong?

    Thanks,
    D

    As an offthread - is there isssues with Latex? If I change the '\' to '/' on the terminating MATH, I get latex compile errors. I get it on every computer. see below

    "Where did I go wrong?" Here:

    The fractions don't have the same numitor, you can't add them that way.

    The answer ^^
