8-x=2y
Swap sides so that all variable terms are on the left hand side.
-x=2y-8
Subtract 8 from both sides.
\frac{-x}{-1}=\frac{2y-8}{-1}
Divide both sides by -1.
x=\frac{2y-8}{-1}
Dividing by -1 undoes the multiplication by -1.
x=8-2y
Divide -8+2y by -1.
2y=8-x
The equation is in standard form.
\frac{2y}{2}=\frac{8-x}{2}
Divide both sides by 2.
y=\frac{8-x}{2}
Dividing by 2 undoes the multiplication by 2.
y=-\frac{x}{2}+4
Divide 8-x by 2.
