Solve for x: −4|x + 5| = −16

Mathematics
1 answer:
Annette [7]3 years ago
3 0
-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
