Answer

The solutions are $s=-3$ and $s=-15$. The graph is shown below.

Work Step by Step

The given equation is $\Rightarrow -4|s+9|=-24$ Divide each side by $-4$. $\Rightarrow \frac{-4|s+9|}{-4}=\frac{-24}{-4}$ Simplify. $\Rightarrow |s+9|=6$ Write related linear equations. $\Rightarrow s+9=6$ or $s+9=-6$ Subtract $9$ from each side. $\Rightarrow s+9-9=6-9$ or $s+9-9=-6-9$ Simplify. $\Rightarrow s=-3$ or $s=-15$ The solutions are $s=-3$ and $s=-15$.
