WIllow solves the equation 12 - p = 16 and gets that p = 4. What did she do wrong?
Find the correct answer please
A.She added 12 to both sides.
B. She did not divide both sides by 12.
C.She did not multiply both sides by 12.
D. She did not divide both sides by -1.
B. She did not divide both sides by -1.
The correct way to solve the equation is as follows:
12 - p = 16
Subtract 12 from both sides:
12 - 12 - p = 16 - 12
-p = 4
Divide both sides by -1:
p = -4
Therefore, the correct answer is p = -4. Willow's mistake was not dividing both sides by -1 to get the correct value of p.
