Answer:

answer: b) x = 3, x = -1

Step-by-step explanation:

3|2x - 2| + 6 = 18.

|2x - 2| + 2 = 6

add -2 : |2x - 2| = 4

2x-2=4 or 2x-2=-4

2x=6 or 2x=-2

x=3 or x=-1

Answer:

b

Step-by-step explanation:

3|2x-2| = 18-6

|2x-2| = 12/3

|2x-2|=4

2x-2 =+-4

2x -2 = -4

2x= -4+2

2x=-2

x=-1

2x -2 = 4

2x= 4+2

2x=6

x=3
