2x=-21-7y
Subtract 7y from both sides.
2x=-7y-21
The equation is in standard form.
\frac{2x}{2}=\frac{-7y-21}{2}
Divide both sides by 2.
x=\frac{-7y-21}{2}
Dividing by 2 undoes the multiplication by 2.
7y=-21-2x
Subtract 2x from both sides.
7y=-2x-21
The equation is in standard form.
\frac{7y}{7}=\frac{-2x-21}{7}
Divide both sides by 7.
y=\frac{-2x-21}{7}
Dividing by 7 undoes the multiplication by 7.
y=-\frac{2x}{7}-3
Divide -21-2x by 7.
