Answer 2

To solve this problem, let's break it down step by step.

Let's assume the number of books on the second shelf initially is x.

According to the problem, the number of books on the first shelf is 3 times the number of books on the second shelf. So, the number of books on the first shelf initially is 3x.

When 18 books are removed from the first shelf and placed on the second shelf, the number of books on both shelves becomes equal.

To find the initial number of books on the second shelf, we need to solve the equation:

3x - 18 = x

Simplifying the equation, we get:

2x = 18

Dividing both sides of the equation by 2, we find:

x = 9

Therefore, the initial number of books on the second shelf was 9.
