Question

The senior classes at High School A and High School B planned separate trips to New York City.
The senior class at High School A rented and filled 4 vans and 6 buses with 360 students. High
School B rented and filled 3 vans and 3 buses with 195 students. Every van had the same
number of students in it as did the buses. Find the number of students in each van and in each
bus.

Answer 1

Use elimination or substitution here
Make children in vans variable V and buses B
4v + 6b =360
-2(3v + 3b = 195) > I multiplied it by -2 so the bs can cross out and I can find the value of v
4v + 6b = 360
-6v -6b = -390
Add straight down
-2v = -30 )))))) v= 15
Now plug in 15 for v in one of the equations above and solve for b
Best of luck!
