Answer:
31 seats
Step-by-step explanation:
Let x be the smaller van, and y be the larger one.
We know that y = x + 14
We also know that 2x + y = 65
If we replace y by its value in the second equation we have:
2x + (x + 14) = 65, then we solve
2x + x + 14 = 65
3x + 14 = 65
3x = 51
x = 17
We now know the smaller van has 17 seats.
To find how many seats are in the big one, we take the first equation:
y = x + 14
y = 17 + 14
y = 31
