9 first class tickets and 8 coach tickets

Step-by-step explanation:

c + f = 17c = 17 - f

270c + 1140f = 12,420

270(17 - f) + 1140f = 12,420

4590 - 270f + 1140f = 12,420

-270f + 1140f = 12,420 - 4590

870f = 7830

f = 7830 / 870

f = 9 < 9 first class tickets

c + f = 17

c + 9 = 17

c = 17 - 9

c = 8 < 8 coach tickets
