Problem Analysis

We have two shelves with a total of 64 books. After moving 2 books from the first shelf to the second shelf, the number of books on each shelf became equal. We need to determine the initial number of books on each shelf.

Solution

Let's assume the initial number of books on the first shelf is x. Therefore, the initial number of books on the second shelf would be 64 - x.

After moving 2 books from the first shelf to the second shelf, the number of books on each shelf became equal. This means that the number of books on the first shelf decreased by 2, and the number of books on the second shelf increased by 2.

So, we can set up the following equation:

x - 2 = 64 - x + 2

Simplifying the equation:

2x - 2 = 66 - x

Adding x to both sides:

3x - 2 = 66

Adding 2 to both sides:

3x = 68

Dividing both sides by 3:

x = 22.67

Since we cannot have a fraction of a book, we can round x to the nearest whole number. Therefore, the initial number of books on each shelf was:

First shelf: 23 books Second shelf: 41 books

Answer

The initial number of books on each shelf was 23 and 41, respectively.
