Answer:
= -1 and
= -9
Explanation:
1. Write the equation to solve:
−4|x + 5| = −16
2. Pass the -4 to divide the -16
|x + 5| =

|x + 5| = 4
3. As you have an absolute value you should solve to equations, that is:
x+5 = 4 (Eq.1)
-x-5 = 4 (Eq. 2)
4. Solve Eq. 1:
x+5 = 4
x = 4-5
x = -1
5. Solve Eq. 2:
-x-5 = 4
x = -5 - 4
x = -9
Therefore the x values are:
= -1 and
= -9
