14-2x=2y
Swap sides so that all variable terms are on the left hand side.
-2x=2y-14
Subtract 14 from both sides.
\frac{-2x}{-2}=\frac{2y-14}{-2}
Divide both sides by -2.
x=\frac{2y-14}{-2}
Dividing by -2 undoes the multiplication by -2.
x=7-y
Divide -14+2y by -2.
2y=14-2x
The equation is in standard form.
\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.
