Answer: The solutions to the equation 2|2x - 2| + 4 = 20 are x = 5 and x = -3

Explanation:

Step 1: Subtract 4 from both sides of the equation:

2|2x - 2| = 16

Step 2: Divide both sides of the equation by 2:

|2x - 2| = 8

Step 3: We now have two cases to consider since the absolute value can result in two possible solutions:

Case 1: 2x - 2 = 8

Solve for x:

2x = 8 + 2

2x = 10

x = 10/2

x = 5

Case 2: -(2x - 2) = 8

Solve for x:

-2x + 2 = 8

-2x = 8 - 2

-2x = 6

x = 6/(-2)

x = -3

Therefore, the solutions to the equation 2|2x - 2| + 4 = 20 are x = 5 and x = -3
