the senior class at highschool a and highschool b planned separate trips to the local amusement park the senior class at highschool a rented and filled 5 vans and 8 buses with 357 students highschoolb rented and filled 10 vans and 5 buses with 285 students every van had the same number of students in it as did the buses find the number of students in each vans and in each bus

solve:
5v + 8b = 357
10v + 5b = 285  > 2v + b = 57
then b = 572v
sub into the first
5v + 8(572v) = 357
5v  16v = 99
v = 99/11 = 9
then b= 572(9) = 39
A van holds 9 students and a bus holds 39 students
