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