Problem Analysis

We are given the information that Sasha has three times more stamps with portraits of Russian writers than Petya. Additionally, Petya has four fewer stamps of this kind than Sasha. We need to determine how many stamps Petya has.

Solution

Let's assume that Petya has x stamps with portraits of Russian writers. According to the given information, Sasha has three times more stamps, so Sasha has 3x stamps.

We are also told that Petya has four fewer stamps of this kind than Sasha. This means that Sasha has 4 + x stamps.

To find the value of x, we can set up an equation based on the given information:

3x = 4 + x

Simplifying the equation:

2x = 4

Dividing both sides by 2:

x = 2

Therefore, Petya has 2 stamps with portraits of Russian writers.

Answer

Petya has 2 stamps with portraits of Russian writers.
