Lets start with the 2nd flight.

Number of seats on the 2nd plane: X
Number of seats on the 1st plane : X+85
Number of seats on the 3rd plane: X-51

Total number of seats = 436.
436= (x)+(x+85)+(x-51)
436= 3x+34
436-34=3x
402=3x
402/3=x = 134- on 2nd plane.
134+85= 219 on 1st plane.
134-51 = 83 on the 3rd plane.

Quick Check
134+219+83= 436
436=436! So, our answer is correct!
