Question

Дедушке 58 лет,его сыну 32 года,внукам 11 и 7 лет.Через сколько лет возраст дедушки будет равен сумме возрастов его сына и внуков?

Answer 1

58 + x = (32 +x) + (11+x) +(7+x)

58 + x = 32 + 11 + 7 + x + x + x

58 + x = 50 + 3x

58 - 50 = 3x - x

2x = 8

x = 4

Ответ: через 4 года.

Answer 2

Calculating the Age

To calculate the number of years until the grandfather's age equals the sum of his son's and grandsons' ages, we can use the following approach:

1. Let's denote the grandfather's age as G, his son's age as S, and the combined age of his grandsons as C. 2. We need to find the number of years x such that G + x = S + C.

Solution

Given: - Grandfather's age (G) = 58 years - Son's age (S) = 32 years - Combined age of grandsons (C) = 11 + 7 = 18 years

We need to find the number of years (x) such that G + x = S + C.

Using the given values: 58 + x = 32 + 18 x = 32 + 18 - 58 x = 50 - 58 x = -8

The negative result indicates that the grandfather's age will never be equal to the sum of his son's and grandsons' ages. This is because the grandfather's age will always be greater than the combined age of his son and grandsons.

Therefore, the grandfather's age will never be equal to the sum of his son's and grandsons' ages.
