Question

Лена старше Ани на 10 лет а Юли на 8 сколько лет Лене.

Answer 1

Ну здесь можно методом подбора... начиная с 11 лет Лене, тогда Ане будет 1 год, а Юле 3года   
Если Лене 18 лет, то Ане 8лет, а Юле 10лет

Answer 2

Calculating Lena's Age

To calculate Lena's age, we can use the information provided. Lena is 10 years older than Ani and 8 years older than Yuli. Let's denote Lena's age as L, Ani's age as A, and Yuli's age as Y.

We can express the given information in the form of equations: 1. L = A + 10 2. L = Y + 8

To find Lena's age, we can solve these equations simultaneously.

Solving for Lena's Age

Substituting the value of L from equation 1 into equation 2: A + 10 = Y + 8

This simplifies to: A = Y - 2

Now, we know that the age difference between Ani and Yuli is 2 years. However, without the specific ages of Ani or Yuli, we cannot determine Lena's exact age.

Given the information provided, we can't determine Lena's age without the specific ages of Ani or Yuli.
