Answer
x = -3
Work Step by Step
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
