Answer 2

Answer: 9 first-class tickets and 3 coach tickets

Explanation:

Let's set up a systems of equation because we have two different values involved: first-class and coach.

f + c = 12

350f + 1080c = 6390

For ease of the equation, let's use the first equation to isolate a variable and plug it into the second one. We'll isolate f:

f = 12 - c

350(12 - c) + 1080c = 6390

c = 3

Now, plug in 3 for the first equation, and f = 9.

There are 9 first-class tickets and 3 coach tickets.
