Answer:
v = how many students fit into a van
b = how many students fit into a bus
School A:
11v+10b=629
School B:
14v+10b=656
Since both classes used 10 buses, we can use elimination by subtracting the A class equation from the B class equation and solve for v, for its value. Then, use either equation and the now found value for v to solve for b.
You should find part of the process to be:
14v%2B10b-%2811v%2B10b%29=656-629, which shows the van holds only a few people even before continuing the solution. (Looks like 9 students fit in a van.)
