Right.
6n + 4 = n - 11
6n + n = 11 - 4
5n = 7
n = 2

is it correct???? (sorry but I'm trying to do the problems and I'm just making sure to see if I'm correct so I may post a few problems, don't worry not too much)
No. You forgot the minus sign.

6n + 4 = n - 11

5n = -4 - 11

5n = -15

n = -3
how did you got -3???? i got 3
Did you check your answer to make sure it satisfies the original equation?

-3 does, 3 does not.
