Answer 1

Алеша- х марок
Боря-  3*х марок
Вася -3*3*х
х+3х+3*3х=52
13*х=52
х=4  у Алеши
3х=3*4=12  у Бори
3*3х=3*3*4=36  у Васи

Answer 2

Solution:

Let's solve this problem step by step.

1. Let's denote the number of stamps Alёsha has as A, the number of stamps Borya has as B, and the number of stamps Vasya has as V.

2. We are given the following information: - A + B + V = 52 (The total number of stamps they have together is 52) - B = 3A (Borya has three times as many stamps as Alёsha) - V = 3B (Vasya has three times as many stamps as Borya)

3. Using the given information, we can form a system of equations to solve for the number of stamps each boy has.

- From B = 3A, we can substitute the value of B in terms of A into the equation A + B + V = 52 to get: A + 3A + 9A = 52 - Simplifying, we get: 13A = 52 - Solving for A, we get: A = 4 - Substituting the value of A back into the equations B = 3A and V = 3B, we get: B = 12 and V = 36

Answer:

So, the number of stamps each boy has is: - Alёsha has 4 stamps - Borya has 12 stamps - Vasya has 36 stamps
