Jerry had some action figures on a shelf in his room. Later he added w more action figures to the shelf. If there are a total of x action figures on his shelf now How many action figures did he have initially on the shelf?

Let's denote the number of action figures that Jerry had on the shelf initially by y.

Jerry had y action figures on a shelf in his room. Later he added w more action figures to the shelf. If there are a total of x action figures on his shelf now

y + w = x

So, we can say that

x - w = y

That is, the number of action figures that Jerry had on the shelf initially is equal to the current number of action figures on the shelf minus the number of action figures that he added later.
