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

asked by bob
  1. solve:
    5v + 8b = 357
    10v + 5b = 285 --- > 2v + b = 57
    then b = 57-2v

    sub into the first
    5v + 8(57-2v) = 357
    5v - 16v = -99
    v = -99/-11 = 9
    then b= 57-2(9) = 39

    A van holds 9 students and a bus holds 39 students
