300=100+7n-77
Use the distributive property to multiply n-11 by 7.
300=23+7n
Subtract 77 from 100 to get 23.
23+7n=300
Swap sides so that all variable terms are on the left hand side.
7n=300-23
Subtract 23 from both sides.
7n=277
Subtract 23 from 300 to get 277.
n=\frac{277}{7}
Divide both sides by 7.
