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
