2x+20=8y+60
Swap sides so that all variable terms are on the left hand side.
2x=8y+60-20
Subtract 20 from both sides.
2x=8y+40
Subtract 20 from 60 to get 40.
\frac{2x}{2}=\frac{8y+40}{2}
Divide both sides by 2.
x=\frac{8y+40}{2}
Dividing by 2 undoes the multiplication by 2.
x=4y+20
Divide 40+8y by 2.
8y=2x+20-60
Subtract 60 from both sides.
8y=2x-40
Subtract 60 from 20 to get -40.
\frac{8y}{8}=\frac{2x-40}{8}
Divide both sides by 8.
y=\frac{2x-40}{8}
Dividing by 8 undoes the multiplication by 8.
y=\frac{x}{4}-5
Divide -40+2x by 8.
