The senior classes at High School A and High School B planned separate trips to the state fair. The senior class at High School A rented and filled 9 vans and 7 buses with 263 students. High School B rented and filled 8 vans and 9 buses with 306 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus. ​ Write a system of equations that can be used to determine v, the number of students that can fit into a van and b, the number of students that can fit into a bus
