\[ \begin{aligned} \frac{x}{-2} = -20 ~ & \textcolor{red}{ \text{ Original equation.}} \\ -2 \left( \frac{x}{-2} \right) - -2 (-20) ~ & \textcolor{red}{ \text{ Multiply both sides by } -2.} \\ x = 40 ...x−2=−20 Original equation.−2(x−2)−−2(−20) Multiply both sides by −2.x=40 On the left, x divided by −2, multiplied by −2, the result is x. On the right, −2(−20)=40.
