Answer
$w=-18$
Work Step by Step
Use the Multiplication Property of Equality by multiplying $-3$ to both sides of the equation:
$$\begin{align*}
\frac{w}{-3} \cdot (-3)&=6(-3)\\
w&=-18\end{align*}$$
Check the solution by substituting $-18$ to the variable in the given equation:
$$\begin{align*}
\frac{w}{-3}&=6\\
\frac{-18}{-3}&\stackrel{?}{=}6\\
6&\stackrel{\checkmark}{=}6\end{align*}$$
Thus, the solution is $w=-18$.
