x=33-5y-2
Subtract 2 from both sides.
x=31-5y
Subtract 2 from 33 to get 31.
33-5y=2+x
Swap sides so that all variable terms are on the left hand side.
-5y=2+x-33
Subtract 33 from both sides.
-5y=-31+x
Subtract 33 from 2 to get -31.
-5y=x-31
The equation is in standard form.
\frac{-5y}{-5}=\frac{x-31}{-5}
Divide both sides by -5.
y=\frac{x-31}{-5}
Dividing by -5 undoes the multiplication by -5.
y=\frac{31-x}{5}
Divide -31+x by -5.
