Problem Analysis

We are given the information that a group of children brought books to a kindergarten. Vova brought 7 more books than Sasha, but 6 fewer books than Olya. In total, the children brought 32 books. We need to determine how many books Olya brought.

Solution

Let's assume that Sasha brought x books. According to the information given, Vova brought 7 more books than Sasha, so Vova brought x + 7 books. Additionally, Vova brought 6 fewer books than Olya, so Olya brought x + 7 + 6 = x + 13 books.

The total number of books brought by all the children is 32. Therefore, we can write the equation:

x + (x + 7) + (x + 13) = 32

Now, let's solve this equation to find the value of x, which represents the number of books Sasha brought.
