-1|3x-2|=7. |3x-2| is the absolute value. Breaking free of the parentheses it looks either as (3x - 2) if 3x - 2 > 0 and the equation is -1(3x-2)=7 or (2 - 3x) = -(3x - 2) if 3x - 2 < 0,and the equation would look as -1(2-3x)=7. Hence you have two equations in one that is due to the fact that the absolute value can hide both negative and positive values of the same number or expression.
