I found: $2 N$ $2N$ to the left.

Explanation:

You have a vectorial composition of your forces:
considering "right" as positive direction you get:

Formally speaking you have the composition of three forces:
${\to F}_{1} = (5 N) \to i$ $vecF_1=(5N)veci$
${\to F}_{2} = (- 3 N) \to i$ $vecF_2=(-3N)veci$
${\to F}_{3} = (- 4 N) \to i$ $vecF_3=(-4N)veci$
Resultant:
$SigmavecF=vecF_1+vecF_2+vecF_3=(5N)veci+(-3N)veci+(-4N)veci=(-2N)veci$ to the left.
