Steven has w peaches. Jake has x fewer peaches than Steven who has y more peaches than Jill. How many peaches does Jill have?
First, we need to find out how many peaches Steven has. We know that Jake has x fewer peaches than Steven, and we know that Steven has y more peaches than Jill. This means that Steven must have (x + y) peaches. 

Now, we need to find out how many peaches Jill has. We know that Steven has (x + y) peaches, and we know that Steven has y more peaches than Jill. This means that Jill must have (x + y - y) peaches. 

This means that Jill has x peaches.

Therefore, the answer (symbolic expression) is: 

x
