Question

can someone help me?
Solve for x: −4|x + 5| = −16

Answer 1

same with\[|x+5| = 4\] since you can divide both side with -4.
\[x+5=4 \] \[x+5=-4 \]

then just solve those.

Answer 2

\(\bf -4|x + 5| = -16\implies |x + 5| =\cfrac{\cancel{ -16 }}{\cancel{ -4 }}
\\ \quad \\
|x + 5| =4\to
\begin{cases}
+(x+5)=4\\
\bf -(x+5)=4
\end{cases}\)

Answer 3

and since its a absolute value you need two answers so make the next one equal to positive 16 and to the same steps
