Also, the trip is going to take 11 hours.
I got a formula of: 11 = 2400/450+x + 2400/450-x
I got 10.7 with decimals but any other help would be great.
Suppose you are flying from Pittsburgh, PA to Los Angeles, CA. The distance between the cities is 2,400 miles and the plane's speed is 450 mi/hr. What is the speed of the wind?
Any help?

looks good, except that online, due to formatting handicaps, you should use parentheses to remove ambiguity:
11 = 2400/(450+x) + 2400/(450-x)
11 = 2400/(450+x) + 2400/(450-x)
I was told that the wind speed is 50, but I'm not sure how to get there.
the wind speed is clearly not 50, since
2400/500 + 2400/400 = 10.8, not 11
You have solved for a round trip. The problem didn't say that, but taking 11 hours for one-way means a speed of about 218 mph, too slow.
Something is screwy with this problem.
Solving your equation gives x ≈ 78.335
2400/500 + 2400/400 = 10.8, not 11

Right? I got that also. I used an online calc and I got 150 sqrt 33/11 to get x ~= 78.335!
