Question

На двух полках было одинаковое количество книг. После того как с одной полки переложили шесть книг, количество книг на одной полке стало в два раза больше, чем на другой. Сколько всего книг на двух полках ?

Answer 1

пусть на полках стояло по х книг, тогда

(х-6)*2 =х

2х- 12= х

2х-х =12

х=12 книг стояло на полках первоначально

12-6=6 книг осталось на второй полке

всего на двух полках стало  12+6 =18 книг

Answer 2

Problem Analysis

We are given that there were an equal number of books on two shelves. After transferring six books from one shelf to the other, the number of books on one shelf became twice the number on the other shelf. We need to determine the total number of books on both shelves.

Solution

Let's assume the initial number of books on each shelf is x. After transferring six books from one shelf to the other, the number of books on one shelf becomes 2x and the number of books on the other shelf becomes x - 6.

According to the given information, we can set up the following equation:

x - 6 = 2x

To solve this equation, we can subtract x from both sides:

-6 = x

Therefore, the initial number of books on each shelf is -6.
