Problem Analysis

We are given that there were 5 fewer cups on the first shelf than on the second shelf. After adding 10 cups to the first shelf and 2 cups to the second shelf, the number of cups on both shelves became equal. We need to determine the initial number of cups on each shelf.

Solution

Let's assume the initial number of cups on the second shelf is x. Since there were 5 fewer cups on the first shelf, the initial number of cups on the first shelf would be x - 5.

After adding 10 cups to the first shelf, the total number of cups on the first shelf becomes (x - 5) + 10 = x + 5.

After adding 2 cups to the second shelf, the total number of cups on the second shelf becomes x + 2.

Since the number of cups on both shelves became equal, we can set up the following equation:

x + 5 = x + 2

Simplifying the equation, we get:

5 = 2

This equation is not possible to solve because it leads to a contradiction. Therefore, there is no solution to this problem.

Conclusion

Based on the given information, it is not possible to determine the initial number of cups on each shelf.
