4х=32
х=8 - возраст Бориса
1,5х=8*1,5=12 - Олег

Answer 2

Problem Analysis

We are given the following information: - Andrei is 4 years older than Oleg. - Oleg is 1.5 times older than Boris. - The sum of their ages is 36 years.

We need to determine the age of each person.

Solution

Let's assign variables to represent the ages of Andrei, Oleg, and Boris.

Let: - Andrei's age be A - Oleg's age be O - Boris's age be B

From the given information, we can write the following equations:

Equation 1: Andrei is 4 years older than Oleg A = O + 4

Equation 2: Oleg is 1.5 times older than Boris O = 1.5B

Equation 3: The sum of their ages is 36 years A + O + B = 36

We can solve this system of equations to find the values of A, O,
