If the sum of two numbers is 20 and their difference is 4, what are the numbers?

• 8 and 12

• 10 and 10

• 11 and 9

• 12 and 8

• 5

• 11

• 3

Answer explanation

To solve the equation, add 5 to both sides to isolate x. This gives 3x = 21. Then divide by 3 to find x = 7. Therefore, the correct answer is 7.
