2 first-class tickets and 6 coach-class tickets

Step-by-step explanation:

Coach ticket = $180

first class ticket = $1020

people = 8

Let x be number of coach tickets

Then number of first class tickets = (8 - x)

x * 180 + (8 - x) * 1020 = 3120

180 X + 8 * 1020 - 1020 x = 3120

180 x + 8160 - 1020 x = 3120

180 x - 1020 x = 3120 -8160

- 840 x = - 5040

840 x = 5040

x = 6

So 6 coach class tickets and 2 first class tickets
