How do you do these probelms?

1. 7p+11=-31
2. 12-7y=-2
3. 2z-4-z=4
4. 10-5h+2=32
5. 7k-8k=1
6. 10-d=19
7. 9x+5-4x=-20
8. 3-4t+11=2
9. 5b+6-6b+2=19

1. Subtract 11 from both sides, to get rid of the 11. Then solve for p.
7p+11=-31
-11 -11
7p=-42
Then divide by 7 to get rid of the 7.
p=-6
Does that help?
7p+11=-31

7p = -31 - 11
7p = -42
p = -6

Follow this pattern for solving the rest of the problems.

Ms. Sue's response is more clear than mine. My computer didn't put some numbers in the right spot.
