Question

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? (5 points)



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

Answer 1

Can you help me on this one"?

Answer 2

yeah figure out the mistake in 2nd step

Answer 3

i tried but i couldn't figure out the right answer

Answer 4

2(y+8)=4y
2y+16=4y
4y-2y=16
2y=16
y=16/2
y=8
this is your correct answer

Answer 5

now compare it with the above explanation

Answer 6

so that means that the last one is the answer?

Answer 7

absolutely

Answer 8

thank you very much! some other guy could not explain it to me as good as you did. :)
