8x=4+2y
Add 2y to both sides.
8x=2y+4
The equation is in standard form.
\frac{8x}{8}=\frac{2y+4}{8}
Divide both sides by 8.
x=\frac{2y+4}{8}
Dividing by 8 undoes the multiplication by 8.
x=\frac{y}{4}+\frac{1}{2}
Divide 4+2y by 8.
-2y=4-8x
Subtract 8x from both sides.
\frac{-2y}{-2}=\frac{4-8x}{-2}
Divide both sides by -2.
y=\frac{4-8x}{-2}
Dividing by -2 undoes the multiplication by -2.
y=4x-2
Divide 4-8x by -2.
