2) 29 - 19 = 10 открыток во втором альбоме
Ответ: в первом и третьем альбомах по 19 открыток, а во втором альбоме  - 10 открыток

Answer 2

Solution:

Let's solve this step by step.

1. Let's assume the number of postcards in the first album is x and in the third album is also x. 2. We are given that the total number of postcards in the first and second albums together is 29.

Calculation:

- Let's represent the number of postcards in the second album as y. - So, the total number of postcards in the first and second albums together is x + y = 29.

Relationship between the albums:

- Since the number of postcards in the first and third albums is the same, we can represent it as x.

Final Equation:

- Therefore, the number of postcards in the second album is 29 - x.

Conclusion:

- The number of postcards in the second album is 29 - x.

Let's calculate the value of x using the given information.

Calculation:

- We know that the total number of postcards in the first and third albums is 48. - So, 2x = 48. - Therefore, x = 24.

Final Answer:

- The number of postcards in the second album is 29 - 24 = 5.

So, there are 5 postcards in the second album.
