Adam could fit w action figures on each shelf in his room. His room has could hold x action figures. How many total shelves did his room have?
First, we need to find out how many action figures can fit on each shelf. We know that Adam can fit w action figures on each shelf, and we know that his room can hold x action figures. This means that the room must have x/w shelves. 

Now, we need to find out how many total shelves there are in the room. To do this, we need to divide the number of action figures by the number of action figures that can fit on each shelf. We know that there are x action figures, and we know that each shelf can hold w action figures. This means that there are x/w shelves in the room. 

Therefore, the answer (symbolic expression) is: 

x/w
