Problem Analysis

We are given that before the start of sales in the second store, there were twice as many chairs as in the first store. After selling 7 chairs from the first store and 34 chairs from the second store, the number of chairs in both stores became equal. We need to find the initial number of chairs in the first store.

Solution

Let's assume the initial number of chairs in the first store is x. According to the problem, the initial number of chairs in the second store is twice that of the first store, so it is 2x.

After selling 7 chairs from the first store, the number of chairs remaining in the first store is x - 7. After selling 34 chairs from the second store, the number of chairs remaining in the second store is 2x - 34.

Since the number of chairs in both stores became equal, we can set up the following equation:

x - 7 = 2x - 34

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

x - 7 = 2x - 34

x - 2x = -34 + 7

-x = -27

x = 27

Therefore, the initial number of chairs in the first store was 27.

Answer

The initial number of chairs in the first store was 27.
