Zack used these steps to solve this equation: When Zack checked his solution, it didn't work. What
was his mistake?
u+5-- -9
Step 1: y + 5- -9
Step 2: y = -14
Siep 3 ()y-4()
O In step 1, he should have used the multiplication
property of equality.
O In step 2, he should havea constant of- 4 on the
right side.
O In step 3, he should have divided both sides by
O In step4, the answer should be positive.
Step 4: y=-21
