Calculating Ania's Age in 2 Years

To calculate Ania's age in 2 years, we can use the information provided about Polina and Ania's current ages and the total of their ages.

Polina is 9 years older than Ania and together they are 15 years old.

Let's calculate Ania's age in 2 years.

Solution

If Polina is 9 years older than Ania, and together they are 15 years old, we can set up the following equations: 1. Ania's age + Polina's age = 15 2. Polina's age = Ania's age + 9

We can solve these equations to find Ania's current age and then calculate her age in 2 years.

Ania's current age can be found by substituting the value of Polina's age from the second equation into the first equation: Ania's age + (Ania's age + 9) = 15 2 * Ania's age + 9 = 15 2 * Ania's age = 15 - 9 2 * Ania's age = 6 Ania's age = 6 / 2 Ania's current age is 3 years.

To find Ania's age in 2 years, we simply add 2 to her current age: Ania will be 5 years old in 2 years.

Conclusion

Ania is currently 3 years old, and she will be 5 years old in 2 years.
