-2x=14-2y
Subtract 2y from both sides.
\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=y-7
Divide 14-2y by -2.
2y=14+2x
Add 2x to both sides.
2y=2x+14
The equation is in standard form.
\frac{2y}{2}=\frac{2x+14}{2}
Divide both sides by 2.
y=\frac{2x+14}{2}
Dividing by 2 undoes the multiplication by 2.
y=x+7
Divide 14+2x by 2.
