Answer 2

Problem Analysis

We are given the following information: - Sasha and Olya together are 38 years old. - Lena and Olya together are 44 years old. - All three sisters together are 65 years old.

We need to determine the age of each sister.

Solution

Let's assume the ages of Sasha, Lena, and Olya are represented by the variables S, L, and O, respectively.

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

1. S + O = 38 (Sasha and Olya together are 38 years old) 2. L + O = 44 (Lena and Olya together are 44 years old) 3. S + L + O = 65 (All three sisters together are 65 years old)

To solve these equations, we can use substitution or elimination method. Let's use the elimination method.

Subtracting equation 1 from equation 3, we get:

(S + L + O) - (S + O) = 65 - 38 L = 27

Substituting the value of L in equation 2, we get:

27 + O = 44 O = 44 - 27 O = 17

Substituting the values of L and O in equation 1, we get:

S + 17 = 38 S = 38 - 17 S = 21

Therefore, the ages of the sisters are: - Sasha is 21 years old. - Lena is 27 years old. - Olya is 17 years old.

Answer

Sasha is 21 years old, Lena is 27 years old, and Olya is 17 years old.
