We are given equation 4x-2y=8.
We need to solve it for y.
In order to solve it for y, we need to get rid all terms from left side and isolate it for y on left side.
4x is added on left side of the equation.
The reverse operation of addition is subtraction.
Subtracting 4x from both sides, we get
4x-4x-2y=8-4x.
-2y = 8 -4x.
We have -2 in front of y. So, we need to get rid -2 from left side.
Dividing by -2 on both sides, we get
-2y/-2 = 8/-2 -4x/-2
y= -4+2x.
Let us write 2x term first, we get
y=2x-4.
Therefore, final equation is y=2x-4.
