y-220=2x-120
Use the distributive property to multiply 2 by x-60.
2x-120=y-220
Swap sides so that all variable terms are on the left hand side.
2x=y-220+120
Add 120 to both sides.
2x=y-100
Add -220 and 120 to get -100.
\frac{2x}{2}=\frac{y-100}{2}
Divide both sides by 2.
x=\frac{y-100}{2}
Dividing by 2 undoes the multiplication by 2.
x=\frac{y}{2}-50
Divide y-100 by 2.
y-220=2x-120
Use the distributive property to multiply 2 by x-60.
y=2x-120+220
Add 220 to both sides.
y=2x+100
Add -120 and 220 to get 100.
