2x-2=12-2y
Subtract 2y from both sides.
2x=12-2y+2
Add 2 to both sides.
2x=14-2y
Add 12 and 2 to get 14.
\frac{2x}{2}=\frac{14-2y}{2}
Divide both sides by 2.
x=\frac{14-2y}{2}
Dividing by 2 undoes the multiplication by 2.
x=7-y
Divide 14-2y by 2.
2y-2=12-2x
Subtract 2x from both sides.
2y=12-2x+2
Add 2 to both sides.
2y=14-2x
Add 12 and 2 to get 14.
\frac{2y}{2}=\frac{14-2x}{2}
Divide both sides by 2.
y=\frac{14-2x}{2}
Dividing by 2 undoes the multiplication by 2.
y=7-x
Divide 14-2x by 2.
