Answer:

8n-1= 13+n is the equation, n=2 is the answer for the variable.

Explanation:

8n-1= 13+n

Move the variable to one side.

8n-1= 13+n

-1n -1n

7n-1= 13

Now, add to both sides, since that is the opposite of subtracting.

7n-1= 13

+1 +1

Then, divide to both sides by 7 to leave the variable by itself.

7n= 14

7 7

n= 2
