50=100+2n-2
Use the distributive property to multiply n-1 by 2.
50=98+2n
Subtract 2 from 100 to get 98.
98+2n=50
Swap sides so that all variable terms are on the left hand side.
2n=50-98
Subtract 98 from both sides.
2n=-48
Subtract 98 from 50 to get -48.
n=\frac{-48}{2}
Divide both sides by 2.
n=-24
Divide -48 by 2 to get -24.
