Question

Возраст отца больше на 33 года сумма возрастов двух его детей Найдите возраст отца в настоящее время зна я что спустя 3 года его возраст был в два раза больше суммы возрастов детей

Answer 1

Пусть х - возраст отца, y- возраст двух его детей, тогда

x=y+33       сейчас
x+3=2y       через 3 года

x+3=2(x-33)
x+3=2x-66
2x-x=3+66
x=69

ответ отцу сейчас 69 лет

Answer 2

Problem Analysis

We are given that the father's age is 33 years older than the sum of the ages of his two children. We also know that three years ago, the father's age was twice the sum of the ages of his children. We need to find the father's current age.

Solution

Let's assume the current age of one of the children is x. Therefore, the current age of the other child would be x + 33.

According to the given information, three years ago, the father's age was twice the sum of the ages of his children. So, three years ago, the father's age would have been 2(x + (x + 33)).

To find the father's current age, we need to add three years to the age three years ago. Therefore, the father's current age would be 2(x + (x + 33)) + 3.

Let's calculate the father's current age using the given information.

Calculation

The father's current age can be calculated as follows:

Father's current age = 2(x + (x + 33)) + 3

Simplifying the equation:

Father's current age = 2(2x + 33) + 3

Father's current age = 4x + 66 + 3

Father's current age = 4x + 69

Now, we need to find the value of x to determine the father's current age.

Solving for x

We know that the father's current age is 33 years older than the sum of the ages of his two children. Therefore, we can write the equation as:

Father's current age = x + (x + 33) + 33

Simplifying the equation:

Father's current age = 2x + 66

Now, we can equate the two expressions for the father's current age:

4x + 69 = 2x + 66

Simplifying the equation:

2x = -3

x = -3/2

Since age cannot be negative, we can conclude that there is no valid solution for this problem.

Therefore, we cannot determine the father's current age based on the given information.
