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 know that Steven has w peaches. We also know that Jake has x fewer peaches than Steven. So, we can say that Jake has w - x peaches. 

Next, we know that Steven has y more peaches than Jill. So, we can say that Jill has w - y peaches. 

Now, we have all the information we need to solve for Jill's peaches. We know that Jake has w - x peaches and we know that Jill has w - y peaches. We also know that Jake has x fewer peaches than Jill. So, we can say that x = w - y - (w - x), which is the same as saying x = 2w - 2x - y. 

Now that we have an equation for x, we can solve for it. We know that w = x + y + z, so we can plug that in for w in our equation for x. We get x = 2(x + y + z) - 2x - y, which is the same as saying x = 3x + 2y + z - y. 

Now we can solve for x. We get x = y + z.
