Solution: Find the relationship between the coach class seat and the first class seat. Then solve for the unknown.

First class seat = x

Coach class seat = 6x + 5

x + 6x + 5 = 152

7x = 147

x = 21 <======== number of first class seats

6x + 5 = 6 x 21 + 5 = 131 <======== number of coach class seats
