Solve for x: - 4|x + 5| = - 16

a. x = 21 over 4, x = - 11 over 4

b. x = - 1, x = 9

c. x = - 1, x = - 9

d. No solution

-4 | x + 5 | = - 16 ... divide both sides by - 4, eliminating it on the left side

| x + 5 | = - 16/-4

| x + 5 | = 4

x + 5 = 4 - (x + 5) = 4

x = 4 - 5 - x - 5 = 4

x = - 1 - x = 4 + 5

-x = 9

x = - 9

solutions : x = - 1, x = - 9
