Answer: X = 4y + 28

Step-by-step explanation: Our first step will be to solve for x.

To do this, we first add 7 to both sides.

This gives us x/4 = y + 7.

Now we want to multiply each side of the equation by 4.

So we get x/4(4) = 4(y + 7).

On the right, distribute the 4 through the parenthses!

Simplifying from here, we get x = 4y + 28.

So this is our final answer.

Answer:

x = 4y+28

Explanation:

x/4 -7 = y

Solve for x

Add 7 to each side

x/4 -7+7 = y+7

x/4 = (y+7)

Multiply each side by 4

x/4*4 = 4(y+7)

x = 4y+28
