Students are going on a field
trip. a total of 8 vehicles will be
needed for 80 students. each
bus holds 13 students and vans
hold 5 students. find how many
buses and vans were taken.

5 buses and 3 vans were taken.

Step-by-step explanation:

x+y=8

13x+5y=80

x=8-y

13(8-y)+5y=80

104-13y+5y=80

104-8y=80

8y=104-80

8y=24

y=24/8

y=3

x+3=8

x=8-3=5

x=5, y=3. (5, 3)

5 buses and 3 vans were taken.
