N=5
Step-by-step explanation:
The goal is to get “n” on only one side, so you can add 15n to -29n and get -14n.
Then you have 16=86-14n, and now you want to get “n” completely by itself. So, the easiest way is to subtract 86 from 16 and get -70.
Now, you have -70=-14n. To get “n” as a variable by itself, you divide both sides by -14, and -70/-14 is 5.
