Q: Solve the equation. Check your solution.

11 - p = 15
- p = 4 (There was a subtract in front of the p.)
- p = 26 (The subtract was in front of the p, not in front of the 11.)
- p = -4 (Correct)
- p = 6 (Incorrect.)
A: p = -4

Q: Solve the equation. Check your solution.

-9 – w = 2
- w = -11 (Correct)
- w = 11 (There was a negative in front of the w.)
- w = 7 (You need to add 9 to both sides.)
- w = -7 (You need to add 11 to both sides.)
A: w = -11

Q: Solve the equation. Check your solution.

-5 = 16 - y
- y = -21 (There was a negative in front of the y.)
- y = 21 (Correct)
- y = 11 (You need to subtract 16 or add -16 to both sides.)
- y = -11 (You need to subtract 16 or add -16 to both sides.)
A: y = 21
