I would give you the answers but I don't know how to solve the equations and I know how you'll feel about guessing...please help me at least learn how to solve these kind of equations.
Here are the real answers:

2. -6
3. -9
4. 4
5. 2
6. -5x - 44
7. 2x + 12

Trust me I got a 18/18 on the test :)!
i got awnsers is wrong i got 7 out of 18
Let's start with the easiest one, # 15.
3x + 6 = 9
Subtract 6 from both sides. Then divide by 3.
What answer do you get?
