Question

В первом бидоне было в два раза больше молока чем во втором.После того как в первый долили 12 литров молока а из второго взяли 6 литров молока в двух бидонах стало поровну.Сколько было молока первоначально?

Answer 1

Пусть в первом бидоне первоночально было х л молока, тогда во втором 2х л. После того как в первый бидон долили 12 л, в нем стало (12+х) л, а когда из второго взяли 6л,там осталось (2х-6) л. Т.к. после этого в бидонах стало поровну молока, составим и решим уравнение:
х+12=2х-6
-х=-18
х=18 - литров молока в первом бидоне.
Найдем сколько л молока было во втором бидоне:
2х=2*18=36 литров
36+18=54 литра мололка всего было первоначально.
Ответ:54 л

Answer 2

Problem Analysis

We are given two containers, and initially, the first container has twice as much milk as the second container. After pouring 12 liters of milk into the first container and taking 6 liters of milk from the second container, the milk in the two containers becomes equal. We need to determine the initial amount of milk in the first container.

Solution

Let's assume that the initial amount of milk in the second container is x liters. According to the problem, the first container initially had twice as much milk as the second container, so the initial amount of milk in the first container is 2x liters.

After pouring 12 liters of milk into the first container, the amount of milk in the first container becomes 2x + 12 liters. After taking 6 liters of milk from the second container, the amount of milk in the second container becomes x - 6 liters.

Since the milk in the two containers becomes equal, we can set up the following equation:

2x + 12 = x - 6

Simplifying the equation, we get:

2x - x = -6 - 12 x = -18

Since the amount of milk cannot be negative, we can conclude that there was no solution to the problem. It is not possible to determine the initial amount of milk in the first container given the information provided.

Answer: There is no solution to the problem. It is not possible to determine the initial amount of milk in the first container.
