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? A. The equation should be y + 8 = 4y after division by 2; y = 4 B. The equation should be y + 8 = 4y after division by 2; y = 6 C. 2 should be distributed as 2y + 16; y = 4 D. 2 should be distributed as 2y + 16; y = 8

    The key to this is the distributive property, which says that 2(x+y) = 2x+2y

    Just use the distributive property to distribute the 2 for (y+8)

    If 2(x+y)=2x+2y then 2(y+8)=what?

    Just plug in "y" for x and "8" for y

    Can you show me HOW you're getting these numbers? I can't tell what you're doing wrong if you don't give me any work.

    2x+2y=4

    The 2x+2y is just an example of how the distributive property works. It's completely unrelated to the problem.

    Don't add the y and the 8.

    2(y+8)=2(y)+2(8)

    I've already told you. I've explained it several ways. It's not a difficult question, all you need to do is use the distributive property and then get y alone.
