Problem Analysis

We have two shelves, each initially containing 30 books. From one shelf, we take some books, and from the other shelf, we take the same number of books as the remaining books on the first shelf. We need to determine how many books are left on both shelves.

Solution

Let's assume that we take 'x' books from one shelf. Since we take the same number of books from the other shelf as the remaining books on the first shelf, we also take 'x' books from the second shelf.

The number of books left on the first shelf would be 30 - x, and the number of books left on the second shelf would also be 30 - x.

Therefore, the answer is that there are 30 - x books left on both shelves.

Example Calculation

Let's say we take 10 books from one shelf. Then, we would also take 10 books from the other shelf. Therefore, the number of books left on both shelves would be 30 - 10 = 20.

Answer

The number of books left on both shelves is 30 - x, where 'x' represents the number of books taken from one shelf.
