Answer 1

A = 6.

Explanation:

4(3a-4)=56

distribute

12a-16=56

add 16

12a = 72

divide by 12

a = 6

Answer 2

A = 6

Explanation:

4(3A - 4) = 56 (Distribute/multiply the 4 to everything inside the parentheses)

12A - 16 = 56 (Add 16 to both sides to get A on one side)

12A = 72 (Divide both sides by 12 to get A by itself)

A = 6
