Answer:
x = 5 when x >=-9
Step-by-step explanation:
| x + 9 | - 4 = 2x
x + 9 - 4 = 2x
x - 2x = 4 - 9
-x = - 5
x = 5
x < - 9 no solution
| x + 9 | - 4 = 2x
| -10 + 9 | - 4 = 2(-10)
| -1 | - 4 = -20
1 - 4 = -20
-3 = -20
x >= -9 no solution only x = 5
| x + 9 | - 4 = 2x
| -9 + 9 | - 4 = 2(-9)
| -1 | - 4 = -18
1 - 4 = -18
-3 = -18
