    1. A. Add 6 to both sides to solve.

    2. D. If you simplify the a terms you will get 6 = 7 which is never true.

    3. A. Subtract 1.2m from both sides and then divide to solve.

    4. B. If you simplify you get 7 = 7 which is always true.

    5. D. Distribute the 2 and then add the 24 to both sides. Then divide to solve.

    6. A. Simplify the right side and then divide all by two. Then add 16 to both sides and divide by 4.

    7. 3y - 2
