Question

Возраст Гулданы через три года будет в 3 раза больше, чем было 3 года тому назад. Сколько лет сейчас Гулдане? Это задача пож помогите

Answer 1

Х лет  -  сейчас Гульдане
(х + 3) лет  -  будет через 3 года
(х - 3)  -  было 3 года назад

х + 3 = (х - 3) * 3
х + 3 = 3х - 9
х - 3х = - 9 - 3
- 2х = - 12
х = 6 лет - сейчас Гульдане

Проверим:
6 + 3 = (6 - 3) * 3
      9 = 9

Answer 2

Problem Analysis

To solve this problem, we need to determine the current age of Guldana. We are given that in three years, Guldana's age will be three times what it was three years ago. We need to find Guldana's current age.

Solution

Let's assume Guldana's current age is x years. According to the problem, in three years, Guldana's age will be three times what it was three years ago. Mathematically, we can represent this as:

x + 3 = 3 * (x - 3)

Now, let's solve this equation to find the value of x.

Expanding the equation:

x + 3 = 3x - 9

Bringing like terms together:

x - 3x = -9 - 3

Simplifying:

-2x = -12

Dividing both sides by -2:

x = -12 / -2

x = 6

Therefore, Guldana is currently 6 years old.

Conclusion

Based on the given information, Guldana's current age is 6 years.
