Question

Задача Бабушка вместе с внучкой Олей 63 года,а вместе с внучкой Машей 65 лет.Всем им вместе 73 года. Сколько лет каждой из них?

Answer 1

Х+63-х+65-х=73
-х+128=73
-х=-55
х=55

63-55=8
65-55=10
ответ: 8,10,55

Answer 2

Problem:

The problem states that a grandmother and her two granddaughters, Olya and Masha, have a combined age of 73 years. The grandmother and Olya together have a total age of 63 years, while the grandmother and Masha together have a total age of 65 years. We need to determine the age of each individual.

Solution:

Let's assume the age of the grandmother is G years, the age of Olya is O years, and the age of Masha is M years.

According to the problem statement, we have the following equations:

1. G + O = 63 (Equation 1) 2. G + M = 65 (Equation 2) 3. G + O + M = 73 (Equation 3)

To solve these equations, we can use a system of linear equations.

Subtracting Equation 1 from Equation 3, we get: (G + O + M) - (G + O) = 73 - 63 M = 10 (Equation 4)

Substituting the value of M from Equation 4 into Equation 2, we get: G + 10 = 65 G = 55 (Equation 5)

Substituting the value of G from Equation 5 into Equation 1, we get: 55 + O = 63 O = 8 (Equation 6)

Therefore, the grandmother is 55 years old, Olya is 8 years old, and Masha is 10 years old.

Grandmother's age: 55 years Olya's age: 8 years Masha's age: 10 years

Please note that the above solution is based on the given information and the assumption that the ages are in whole numbers.
