Answer:

B.  x = -1 or x = 4 1/3.

Step-by-step explanation:

2|3x -5| -8 =8

2|3x -5| = 16

|3x -5|  =  8

The expression in the vertical lines can be positive or negative so we have 2 equations:

3x - 5 = 8 and 3x - 5 = -8

3x - 5 = 8

3x = 13

x = 13/3 or 4 1/3

3x - 5 = -8

3x = -8 + 5 = -3

x = -1.
