Question

The incorrect work of a student to solve an equation 2(y + 4) = 4y is shown below:

Step 1: 2(y + 4) = 4y
Step 2: 2y + 6 = 4y
Step 3: 2y = 6
Step 4: y = 3

Which of the following explains how to correct Step 2 and shows the correct value of y? (5 points)


The equation should be y + 4 = 4y after division by 2; y = 5

The equation should be y + 4 = 4y after division by 2; y = 2

2 should be distributed as 2y + 8; y = 4

2 should be distributed as 2y + 8; y = 2
