Question

Помогите пожалуйста молю, решите задачу: Через 2 года мой братишка будет в 2 раза старше, чем 2 года назад, а я через 3 года буду в 3 раза старше, чем 3 года назад. Сколько лет брату и сколько мне сейчас?

Answer 1

Пусть x — возраст брата.
Тогда можно составить уравнение: (x+2) = 2 * (x — 2)
x+2 = 2x-4
x = 6 лет брату

Пусть y — ваш возраст
Составляем уравнение
y + 3 = 3 * (y — 3)
y + 3 = 3y — 9
2y = 12
y = 6 — ваш возраст

Таким образом, вам с братом по 6 лет

Answer 2

Problem Analysis

To solve this problem, we need to determine the current ages of the person asking the question and their brother. We are given that in 2 years, the brother will be twice as old as he was 2 years ago, and in 3 years, the person asking the question will be three times as old as they were 3 years ago.

Solution

Let's assume the current age of the person asking the question is x and the current age of their brother is y.

According to the given information: - In 2 years, the brother will be twice as old as he was 2 years ago. This can be represented as: y + 2 = 2(y - 2). - In 3 years, the person asking the question will be three times as old as they were 3 years ago. This can be represented as: x + 3 = 3(x - 3).

We can solve these two equations to find the values of x and y.

Solving the Equations

Let's solve the first equation: y + 2 = 2(y - 2)

Expanding the equation: y + 2 = 2y - 4

Simplifying the equation: y - 2y = -4 - 2 -y = -6 y = 6

Now, let's solve the second equation: x + 3 = 3(x - 3)

Expanding the equation: x + 3 = 3x - 9

Simplifying the equation: x - 3x = -9 - 3 -2x = -12 x = 6

Answer

Based on the calculations, the current age of the person asking the question is 6 years and the current age of their brother is also 6 years.

Please note that these calculations are based on the given information and assumptions made.
