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 Adam could fit on each shelf in his room. We know that Adam could fit w action figures on each shelf, and we know that his room could hold x action figures. This means that the number of shelves in Adam's room must be x/w. 

Now, we need to find out how many total shelves Adam's room had. To do this, we need to divide the number of action figures that Adam's room could hold by the number of action figures that Adam could fit on each shelf. We know that Adam's room could hold x action figures, and we know that Adam could fit w action figures on each shelf. This means that the number of shelves in Adam's room must be x/w. 

Therefore, the answer (symbolic expression) is: 

x/w
