What is the net force on this object?

The 20N straight up exactly cancels the 20N straight down.  So we can see that there's no net vertical force on the object, and if there's ANY net force on it at all, it's going to be horizontal.

The 14N force toward the left can't cancel the whole 22N toward the right.  It can only cancel 14N of it, and then there's still another 8N more toward the right.

So the net force on the object is 8N toward the right.
