Implicit in the way they ask you to put your answer, you know there will be two solutions. Do you know what the vertical bars (  ) stand for?

The vertical bars mean absolute value. When you're evaluating the expression, positive is positive and negative is positive. So, if I want to know x, then answer is 10 if x is 10 *or* 10.

In x = A, you have x= A if x is positive. You have x = A if x is negative. The second consideration is resolved by a double negative.

So, if 3x is positive, you have the equation 3  x = 8 and then you solve that. If 3x is negative, you have (3  x) = 8 or x  3 = 8, and then you solve that one. You will have both as answers.

So, do you understand now how you have to set up 2 equations? one for the positive and one for the negative.
