Answer:
<u>The correct answer is A. Add 4 to both sides, and then divide by 2. The solution is x = 12.</u>
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
<u>The correct answer is A. Add 4 to both sides, and then divide by 2. The solution is x = 12.</u>
