2x=14+2y
Add 2y to both sides.
2x=2y+14
The equation is in standard form.
\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=y+7
Divide 14+2y by 2.
-2y=14-2x
Subtract 2x from both sides.
\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=x-7
Divide 14-2x by -2.
