For a trip, one high school rented and filled 8 vans and 2 buses with 146 students. another high school instead fits its 261 students into 3 vans amd 9 buses. With each bus and van seating the same number if students, how many students can a bus carry? And how many students can a van carry?

I’m really having trouble trying to figure this out, I have tried multiple times but have failed to succeed. Btw this is Algebra 1
