Solve the equation -7 = y for x.
A. x= 4y - 28
B. x = y - 28
C. x = 4y + 28
D. x = 4y + 7

Answer:
x = 4y+28
Step-by-step 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
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.
