\frac{-90}{5}=-4n+2
Divide both sides by 5.
-18=-4n+2
Divide -90 by 5 to get -18.
-4n+2=-18
Swap sides so that all variable terms are on the left hand side.
-4n=-18-2
Subtract 2 from both sides.
-4n=-20
Subtract 2 from -18 to get -20.
n=\frac{-20}{-4}
Divide both sides by -4.
n=5
Divide -20 by -4 to get 5.
