Group the terms with n together, group those with k together. But first, expand the brackets.
12n+(-3k)+2n - 5k
= 12n - 3k + 2n - 5k
= 12n + 2n - 3k - 5k
= 14n - 8k

Add like terms
12n + 2n = 14 n
-5k + (-3k) = -8k
thus you have 14n - 8k

12n + (-3k) + 2n - 5k
12n + 2n + (-3k) - 5k (Rearrange like terms, if you want)
14n - 8k

= 12n + (- 3k) + 2n - 5k
= 12n - 3k + 2n - 5k
= 14n - 8k
