Answer 2

Let's assume that "Summa vozrastov mami i docheri" means "the sum of the ages of the mother and daughter".

Let's call the age of the daughter "x". Then, according to the problem, the age of the mother is 4 times that of the daughter, so the age of the mother is 4x.

The sum of their ages is given to be 35:

x + 4x = 35

Combining like terms, we can simplify the equation:

5x = 35

Dividing both sides by 5, we get:

x = 7

So the daughter is 7 years old.

To find the age of the mother, we can use the fact that the age of the mother is 4 times that of the daughter:

4x = 4 * 7 = 28

Therefore, the mother is 28 years old.

To check, we can verify that the sum of their ages is indeed 35:

7 + 28 = 35

So our solution is correct. The mother is 28 years old, and she is 4 times older than her daughter who is 7 years old.
