Answer: 52 students were in the bus.
Step-by-step explanation: First, you start with the equation:
9x+4=472
Since four students rode in cars, you want to eliminate this part of the problem to find how many students actually rode in the buses.
So you would subtract 4 from both sides and get: 9x=468
Finally, you would divide both sides by 9 and get 52 students on each bus
