Problem Analysis

We are given that the number of books on two shelves was initially the same. When 18 books were moved from the first shelf to the second, the number of books on the second shelf became three times the number on the first shelf. We need to find the initial number of books on each shelf.

Solution

Let's assume the initial number of books on each shelf is x.

According to the given information: - When 18 books were moved from the first shelf to the second, the number of books on the second shelf became three times the number on the first shelf. - So, the number of books on the second shelf is 3x.

We can set up the following equation based on the given information: x - 18 = 3x

Now, let's solve this equation to find the value of x.

Solving the Equation

x - 18 = 3x

Subtract x from both sides: -18 = 2x

Divide both sides by 2: x = -9

Since the number of books cannot be negative, we can conclude that there is no solution to this problem.

Therefore, there is no initial number of books on each shelf that satisfies the given conditions.
