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 $s=-15$.
