Ok, first step is to distribute the h to get rid of parenthesis:

-2n - 4hrx + 6hs -3rx +3s

Then you would combine like terms, but there are none! So that's your answer.

- 2n - h(4rx - 6s) - 3rx + 3s =

= - 2n - h×4rx - h×(- 6s) - 3rx + 3s

= - 2n - 4hrx + 6hs - 3rx + 3s

= 2(3hs - 2hrx - 2) - 3(rx - s)
