9x=-18+y
Add y to both sides.
9x=y-18
The equation is in standard form.
\frac{9x}{9}=\frac{y-18}{9}
Divide both sides by 9.
x=\frac{y-18}{9}
Dividing by 9 undoes the multiplication by 9.
x=\frac{y}{9}-2
Divide -18+y by 9.
-y=-18-9x
Subtract 9x from both sides.
-y=-9x-18
The equation is in standard form.
\frac{-y}{-1}=\frac{-9x-18}{-1}
Divide both sides by -1.
y=\frac{-9x-18}{-1}
Dividing by -1 undoes the multiplication by -1.
y=9x+18
Divide -18-9x by -1.
