Net External Force in a Direction

[Smiley.Teddy]

Homework Statement

A crate is pulled to the right with a force of 92.3 N, to the left with a force of 116.8 N, upward with a force of 508.8 N, and downward with a force of 248. 6 N
What is the net external force in the x direction? Answer in units of N

Homework Equations

When I solved for the Y-Direction I simply subtracted the upward force from the downward force and got the answer correct. I don't know what to do for the x-direction.

The Attempt at a Solution

X direction: I attempted these:
-92.3N-116.8N = -209.1
116.8N-92.3N = 24.5
116.8N^2+92.3N^2 and then square root that answer to get = 148. 867...

Please help me understand what it is that I'm doing wrong. Thank you. =]

(why did you think they might be different? )

For the x-direction, just do exactly what you did for the y-direction.
