Willow made a subtraction error when trying to isolate p on one side of the equation. She should have subtracted 12 from both sides of the equation, not just one side. The correct steps are as follows:
12 - p = 16
Subtract 12 from both sides:
12 - p - 12 = 16 - 12
-p = 4
Multiply both sides by -1 to solve for p:
p = -4
Therefore, the correct answer is p = -4, not p = 4.
willow solves the equation, 12 - p = 16, and gets that p = 4. What did she do wrong?
