All you do is look for like terms such as 7n and 3n; 2 and 8
Then you do 7n+3n=10 n
And ........... 2-8=-6
The answer is 10n-6

Gather like terms. The - 2 and 4; the 7n and 3n. 7n - 2 + 3n + 4 = 10n + 2
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
9n-2=7n+50 7n+9n=50+2 16n=52 n= 3.25
10n + 3 = 7n + 53n = 2n = 2/3
-7n - 8 + 6 = 13 - 2 Add 2 to each side: -7n - 8 + 6 + 2 = 13 simplify: -7n = 13 n = -13/7 = -16/7
