## Prealgebra (7th Edition)

To make this problem more manageable, multiply every number by 10 to eliminate the decimal numbers: 10(0.2x) + 10(1.3) = 10(0.7) 2x + 13 = 7 Now, subtract 13 from both sides: 2x + 13 -13 = 7 - 13 2x = -6 Divide both sides by 2 to get x by itself. $\frac{2x}{2}$ = $\frac{-6}{2}$ x = -3
