-7x=18-2y
Subtract 2y from both sides.
\frac{-7x}{-7}=\frac{18-2y}{-7}
Divide both sides by -7.
x=\frac{18-2y}{-7}
Dividing by -7 undoes the multiplication by -7.
x=\frac{2y-18}{7}
Divide 18-2y by -7.
2y=18+7x
Add 7x to both sides.
2y=7x+18
The equation is in standard form.
\frac{2y}{2}=\frac{7x+18}{2}
Divide both sides by 2.
y=\frac{7x+18}{2}
Dividing by 2 undoes the multiplication by 2.
y=\frac{7x}{2}+9
Divide 18+7x by 2.
