Solve 5n - 20 = 7n - 80

N=30

Step-by-step explanation:

First you subtract 5n from 7n which would give you to 2n on the right side

So then you have - 20=2n-80. Then you add 80 to the left side so you have the variable only on one side. Then you have 60=2n. Then you divide the number from the variable. Which would make 60/2=n then you divide and get 30=n which would be your final answer.

The answer is n = 30
