To solve this, the steps are following $5|2x-7|=20$ (divide both sides by 5) $|2x-7| = 20/5$ $|2x-7| = 4$ ** When we open the absolute bars, there are two values of x as the absolute value of a negative number is also positive. 1. $|2x-7| = 4$ 2x-7 = 4 2x = 11 x=5.5 2. $|2x-7| = 4$ -(2x-7) = 4 2x-7 = -4 2x = 3 x = 1.5 Therefore the values of x are 1.5, 5.5.
