Answer: -6

Step-by-step explanation:

First combine like terms.

6n + 7 = 13 +7n

-7            -7

6n = 6 +7n

-7n       -7n

We want to try to get the numbers on a different side than the variables. Keep this in mind when combining like terms.  Finally we get

Our last step is to divide by negative one to get rid of the -1 from the variable.

-1n = 6

-1/    -1/

Our answer is n = -6
