<u>Answer: </u>

Option (A)

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

<u>Explanation:</u>

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

Step I: Add 4 to both sides

Adding, 2x – 4 + 4 = 20 + 4

2x = 24

Step II: Divide by 2

x = 12

Therefore, solution is x = 12

Hence, option (a) is correct
