Which of the following describes the correct process for solving the equation 2x - 4 = 20 and arrives at the correct solution? Add 4 to both sides, and then divide by 2. The solution is x = 12. Divide both sides by - 4, and then subtract 2. The solution is x = - 7. Subtract 4 from both sides, and then divide by 2. The solution is x = - 12. Multiply both sides by - 4, and then divide by 2. The solution is x = - 40.

The correct answer is A. Add 4 to both sides, and then divide by 2. The solution is x = 12.

Step-by-step explanation:

1. For solving the question and understand which of the statements matches with the solution, let's proceed with the equation:

2x - 4 = 20

2x - 4 + 4 = 20 + 4 (Adding 4 at both sides)

2x = 24

2x/2 = 24/2 (Dividing by 2 at both sides)

x = 12

The correct answer is A. Add 4 to both sides, and then divide by 2. The solution is x = 12.
