Chapter 2 - Section 2.2 - The Multiplication Property of Equality - Exercise Set: 20

Answer

$x=-32$

Work Step by Step

Multiply both sides of the equation by -$\frac{8}{5}$ to isolate the variable. 20=-$\frac{5}{8}$x -$\frac{5}{8}x=20$ $\frac{-5(-8)}{8(5)}$x=-$\frac{20(8)}{5}$ x=-$\frac{4(8)}{1}$ x=-32 Check the answer. -$\frac{5}{8}$(-32)=20 $\frac{5(32)}{8}$=20 $\frac{5(4)}{1}$=20 20=20
