C. 16
D. 48

the answer is 12 because 8 × 6 = 48 ÷ 4 = 12

Explanation:

Answer 2

A. 12

Explanation:

Let the number be A

8 x (A - 6) = 4 x A

Expand the left side

8 x A - 8 x 6 = 4A

8A - 48 = 4A

Add 48 to both sides

8A - 48 + 48 = 4A + 48

8A = 4A + 48

Subtract 4A from both sides

8A - 4A = 4A - 4A + 48

4A = 48

Divide both sides by 4

A = 48/4

A = 12
