Answer:

a = 3b + 13

Explanation:

To solve any equation, you have to place one of the variables (like "a" or "x") to one side of the equal sign, and the rest of the variables and constants (Numbers like 7, 3, or 2) on the other side.

1. a - 7 = 3 (b + 2)

2. a - 7 = 3b + 6 (Distribute the 3 by multiplying it to b and 2)

3. a = 3b + 13 (Add 7 to both sides to remove the -7 on the left and add 7 to 6 on the right)
