Question

СРОЧНО в одном шкафу было в 7 раз меньше книг,чем в другом...Когда в первыйшкаф положили 25 книг,а из второго взяли 29 то в обоих шкафах книг стало поровну,сколько книг было в каждом шкафу?​

Answer 1

Ответ:

Пошаговое объяснение:

Пусть в одном шкафу - х книг, тогда в другом - 7х, когда в первый шкаф положили 25 книг, то в нем стало х+ 25 , а из второго взяли 29, то в нем стало 7х-29. Составим уравнение:

х+25= 7х - 29

-6х= - 54

х= 54 : 6

х= 9 книг в одном шкафу

7х= 7*9= 63 книги в другом шкафу

Answer 2

Solving the Bookshelf Problem

To solve this problem, we can set up a system of equations based on the given information and then solve for the number of books in each bookshelf.

Let's denote: - x as the number of books in the first bookshelf - 7x as the number of books in the second bookshelf (since it was 7 times more than the first)

We are given the following information: 1. When 25 books were added to the first bookshelf and 29 books were taken from the second bookshelf, the number of books became equal in both bookshelves.

We can represent this information in the form of an equation: x + 25 = 7x - 29

Now, let's solve for x to find the number of books in each bookshelf.

Calculating the Number of Books in Each Bookshelf

Subtracting x from both sides of the equation gives us: 25 = 6x - 29

Adding 29 to both sides of the equation gives us: 54 = 6x

Dividing both sides by 6 gives us: x = 9

So, the number of books in the first bookshelf (x) is 9, and the number of books in the second bookshelf (7 times more than the first) is 63.

Therefore, there were 9 books in the first bookshelf and 63 books in the second bookshelf.
