    You said that n/3 = n/2 + 12.

    There's only one number that 'n' can be.

    It may or may not be an integer. We'll have to see.

    Subtract n/2 from each side: n/3 - n/2 = 12

    Multiply each side by 12 : 4n - 6n = 144

    Do the subtraction on the left: - 2n = 144

    Divide each side by - 2 : n = - 72

    Yep. It turns out that 'n' is an integer.

    It didn't have to be, just because you said so.

    For example, if you said that n/3 is only

    11 greater than n/2, we could figure out

    what number 'n' must be, and it wouldn't

    be an integer.
