Question

Сейчас отцу 34 года, а сыну 11 лет. Через сколько лет возраст отца будет в 2 раза больше возраста сына?

Answer 1

Х через сколько лет
34+х=2(11+х)
34+х=22+2х
х=12 лет через 12 лет

Answer 2

Через 12 лет
34+12=46
11+12=26
46÷26=2

Answer 3

Calculation of the Father's Age

To determine the number of years it will take for the father's age to be twice that of the son's age, we can set up the following equation:

Father's Age + x = 2 * (Son's Age + x)

Where x represents the number of years in the future.

Let's solve this equation to find the value of x:

34 + x = 2 * (11 + x)

Expanding the equation:

34 + x = 22 + 2x

Simplifying the equation:

34 - 22 = 2x - x

12 = x

Therefore, it will take 12 years for the father's age to be twice that of the son's age.

Answer

In 12 years, when the father is 46 years old and the son is 23 years old, the father's age will be twice that of the son's age.
