Question

20 = 8x + 4y what is y?

Answer 1

You have to move the 8x over to the other side to get y by itself. and then divide the 4 from the y to the other side and y should equal y= 2x+5

Answer 2

Answer:

y = -2x + 5

Step-by-step explanation:

20 = 8x + 4y

subtract 8x from both sides

4y = -8x + 20

divide both sides by 4

y = -2x + 5
