Best ResponseYou've already chosen the best response.0Implicit 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?

Best ResponseYou've already chosen the best response.0The 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.

Best ResponseYou've already chosen the best response.0In 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.

Best ResponseYou've already chosen the best response.0So, 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.
