20x-8=4y
Swap sides so that all variable terms are on the left hand side.
20x=4y+8
Add 8 to both sides.
\frac{20x}{20}=\frac{4y+8}{20}
Divide both sides by 20.
x=\frac{4y+8}{20}
Dividing by 20 undoes the multiplication by 20.
x=\frac{y+2}{5}
Divide 8+4y by 20.
4y=20x-8
The equation is in standard form.
\frac{4y}{4}=\frac{20x-8}{4}
Divide both sides by 4.
y=\frac{20x-8}{4}
Dividing by 4 undoes the multiplication by 4.
y=5x-2
Divide 20x-8 by 4.
