-7x=-9+3y
Add 3y to both sides.
-7x=3y-9
The equation is in standard form.
\frac{-7x}{-7}=\frac{3y-9}{-7}
Divide both sides by -7.
x=\frac{3y-9}{-7}
Dividing by -7 undoes the multiplication by -7.
x=\frac{9-3y}{7}
Divide -9+3y by -7.
-3y=-9+7x
Add 7x to both sides.
-3y=7x-9
The equation is in standard form.
\frac{-3y}{-3}=\frac{7x-9}{-3}
Divide both sides by -3.
y=\frac{7x-9}{-3}
Dividing by -3 undoes the multiplication by -3.
y=-\frac{7x}{3}+3
Divide -9+7x by -3.
