A graph shows one solution, at ...

... B. x = 9/2

_____

The equation can be resolved to two:

1. For x < -4

... -(x+4) = 3x -5

... 0 = 4x -1 . . . . . . add x+4

... 0 = x -1/4 . . . . . divide by 4

... 1/4 = x . . . . . . . not in the domain x < -4 . . . . no solution

2. For x ≥ -4

... x+4 = 3x -5

... 0 = 2x -9 . . . . . subtract the left side

... 0 = x -9/2 . . . . divide by 2

... 9/2 = x . . . . . . . in the domain x ≥ -4. This is the solution.
