Question

The steps below show the incomplete solution to find the value of y for the equation 4y − 2y − 4 = −1 + 13:

Step 1: 4y − 2y − 4 = −1 + 13
Step 2: 4y − 2y − 4 = 12
Step 3: 2y − 4 = 12

Which of these is most likely the next step?

2y = 3
2y = 8
2y = 16
2y = 18

Answer 1

2y=16, because 2y-4=12
+4=+4
2y=16

Answer 2

2y=16. This is because
2y-4=12
2y=12+4
2y=16
