-401=-5-4n+4
Use the distributive property to multiply n-1 by -4.
-401=-1-4n
Add -5 and 4 to get -1.
-1-4n=-401
Swap sides so that all variable terms are on the left hand side.
-4n=-401+1
Add 1 to both sides.
-4n=-400
Add -401 and 1 to get -400.
n=\frac{-400}{-4}
Divide both sides by -4.
n=100
Divide -400 by -4 to get 100.
