Problem Statement

We are given that Oleg is 3 times older than Andrei, and Oleg is 8 years older than Andrei. We need to find the ages of both boys.

Solution

Let's assume Andrei's age as x years. According to the problem, Oleg is 3 times older than Andrei, so Oleg's age can be represented as 3x years. Additionally, we are given that Oleg is 8 years older than Andrei.

To solve this problem, we can set up the following equation:

3x = x + 8

Now, let's solve this equation to find the values of x and 3x.

3x - x = 8

Simplifying the equation:

2x = 8

Dividing both sides by 2:

x = 4

So, Andrei is 4 years old.

To find Oleg's age, we substitute the value of x back into the equation:

Oleg's age = 3x = 3 * 4 = 12

Therefore, Andrei is 4 years old and Oleg is 12 years old.
