6x=-27+3y
Add 3y to both sides.
6x=3y-27
The equation is in standard form.
\frac{6x}{6}=\frac{3y-27}{6}
Divide both sides by 6.
x=\frac{3y-27}{6}
Dividing by 6 undoes the multiplication by 6.
x=\frac{y-9}{2}
Divide -27+3y by 6.
-3y=-27-6x
Subtract 6x from both sides.
-3y=-6x-27
The equation is in standard form.
\frac{-3y}{-3}=\frac{-6x-27}{-3}
Divide both sides by -3.
y=\frac{-6x-27}{-3}
Dividing by -3 undoes the multiplication by -3.
y=2x+9
Divide -27-6x by -3.
