It depends! What is the value of N?
Example
If n= 3, the answer would be 11
(3n= 3x3=9 the plus the 2)
Example 2
If n=7, ten the answer would be 23
(3n= 3x7=21 plus the 2wouldbe 23)
Hope this helps

3n+2+3n+2=6n+4
n2-3n+2
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)
2+3n+2+9n would equal 4+12n after adding all like numbers.
