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?

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

Answer 1

Try distributing this.
2(y + 4) = 4y

Answer 2

step 2 i think is 2y+12=4y

Answer 3

thanks!!!!!
