    First, suppose 3x - 7 is greater then 0 and solve 3x - 7 = 12 Then, suppose it is not and solve -(3x - 7) = 12, that is 7 - 3x = 12

    Do what @Andrea_Grossoni said. Solve for x on both equations.

    Is what Andrea said the final answer?

    No. Solve for x in: 3x-7=12 and -(3x-7)=12

    @finiteok , the answer 5/3 is wrong, put 5/3 instead of x in the equation and you'll see The answer is -5/3, and of course 19/3

    I hope that "she" was not referred to me. In Italy it is a male name :D Always a pleasure to help, so I don't feel guilty when I get helped!
