I found: #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:
#vecF_1=(5N)veci#
#vecF_2=(-3N)veci#
#vecF_3=(-4N)veci#
Resultant:
#SigmavecF=vecF_1+vecF_2+vecF_3=(5N)veci+(-3N)veci+(-4N)veci=(-2N)veci# to the left.
