Answer:
Let v = no. of students in a van
b = no. of students in a bus
5v + 6b = 393 7v + 6b = 411
9 students in each van 58 students in each bus
Step-by-step explanation:
Let v = no. of students in a van
b = no. of students in a bus
School A School B
(1) 5v + 6b = 393 (2) 7v + 6b = 411
Change all the signs in (1) to get -5v - 6b = -393
Add that to (2) 7v + 6b = 411
<u>-5v - 6b = -393</u>
2v = 18
v = 9 students in each van
Substitute 9 in for v in (1) and we get 5(9) + 6b = 393
45 + 6b = 393
6b = 348
b = 58 students in each bus
