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

Answer 2

ahahahh the wrong student didn't distribute all the way
2y+8 = 4y
8 = 4y-2y
8 = 2y
4 = y

Answer 3

Your Funny

Answer 4

step 1 is an error already... because through distribution we have 2(y+4) = 2y+8

student must have accidentally did 2+4 after doing 2 x y

Answer 5

So The Answer is C
