Answer 2

Problem Analysis

To solve this problem, we need to find the ages of two girls, Masha and Dasha. We are given that Masha is 3 years older than Dasha, and their combined age is 27 years. We need to determine the age of each girl.

Solution

Let's assume that Dasha's age is represented by the variable x. Since Masha is 3 years older than Dasha, Masha's age can be represented as x + 3.

According to the problem, the sum of their ages is 27 years. We can write this as an equation:

x + (x + 3) = 27

Simplifying the equation, we get:

2x + 3 = 27

Subtracting 3 from both sides of the equation, we have:

2x = 24

Dividing both sides of the equation by 2, we get:

x = 12

Therefore, Dasha is 12 years old. Since Masha is 3 years older, Masha is:

12 + 3 = 15 years old

So, Dasha is 12 years old and Masha is 15 years old.

Answer

Dasha is 12 years old and Masha is 15 years old.
