PLEASE HELP ASAP
The equation (x + 56) / 3 = 5x models the workload of a class project, where x is the number of hours each student must contribute. How many hours does each student work on the project?

I think it's 4 hours because when I plug it into the equation, it shows 20 = 20 indicating it's correct. I need some verification tho.

10 hours
9 hours
7 hours
4 hours
