The incorrect work of a student to solve an equation 2 (y + 8) = 4y is shown below:

Step 1: 2 (y + 8) = 4y

Step 2: 2y + 10 = 4y

Step 3: 2y = 10

Step 4: y = 5

Which of the following explains how to correct Step 2 and shows the correct value of y?

The equation should be y + 8 = 4y after division by 2; y = 4

The equation should be y + 8 = 4y after division by 2; y = 6

2 should be distributed as 2y + 16; y = 4

2 should be distributed as 2y + 16; y = 8
