Solve for x: −4|x + 5| = −16

= -1 and = -9

Step-by-step 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
