4x=14+2y
Add 2y to both sides.
4x=2y+14
The equation is in standard form.
\frac{4x}{4}=\frac{2y+14}{4}
Divide both sides by 4.
x=\frac{2y+14}{4}
Dividing by 4 undoes the multiplication by 4.
x=\frac{y+7}{2}
Divide 14+2y by 4.
-2y=14-4x
Subtract 4x from both sides.
\frac{-2y}{-2}=\frac{14-4x}{-2}
Divide both sides by -2.
y=\frac{14-4x}{-2}
Dividing by -2 undoes the multiplication by -2.
y=2x-7
Divide 14-4x by -2.
