Question

Отец в три раза старше сына.Через 6 лет сумма чисел лет отца и сына будет равна 68.Сколько лет сыну сейчас?

Answer 1

х лет - сыну

3х лет - отцу

 

х+6+зх+6=68

4х+12=68

4х=56

х=14 (лет) сыну

Answer 2

Пусть сыну  x лет, тогда отцу 3x

(x+6)+(3x+6)=68

4x=68-12

4x=56

x=14 лет сыну

Answer 3

Problem Analysis

We are given that the father is three times older than the son. After 6 years, the sum of their ages will be 68. We need to determine the current age of the son.

Solution

Let's assume the current age of the son is x years. According to the problem, the father is three times older than the son, so the current age of the father is 3x years.

After 6 years, the son's age will be x + 6 years, and the father's age will be 3x + 6 years. The sum of their ages will be 68, so we can write the equation:

(x + 6) + (3x + 6) = 68

Simplifying the equation:

4x + 12 = 68

Subtracting 12 from both sides:

4x = 56

Dividing both sides by 4:

x = 14

Therefore, the current age of the son is 14 years.

Answer

The son is currently 14 years old.

Explanation

According to the given information, the father is three times older than the son. After 6 years, the sum of their ages will be 68. By solving the equation, we find that the current age of the son is 14 years.
