First, group the like terms and then combine. See below for the full explanation.

First, group the like terms:

$color(blue)(3) + color(red)(2s) - color(blue)(4) + color(red)(3s) ->$

$color(blue)(3) - color(blue)(4) + color(red)(2s) + color(red)(3s)$

Now, we can combine like terms, the constants and the $s$ terms:

$color(blue)((3 - 4)) + color(red)((2 + 3)s)$

$color(blue)(-1) + color(red)(5s)$

or

$color(red)(5s) - color(blue)(1)$
