Question

В двух грузовых вагонах было поровну угля.Когда из первого вагона выгрузили 12 т угля,а из второго 22 т,то в первом вагоне осталось в 6 раз больше угля,чем во втором.Сколько тонн угля было в каждом вагоне в начале?

Answer 1

Х - было в каждом вагоне
6(х-22)=х-12
6х-132=х-12
6х-х=132-12
5х=120
х=120:5
х=24 (т)
Ответ: вначале в каждом вагоне было 24 т угля

Answer 2

Problem Analysis

We are given two freight wagons with an equal amount of coal. After unloading 12 tons of coal from the first wagon and 22 tons from the second wagon, the first wagon is left with 6 times more coal than the second wagon. We need to determine the initial amount of coal in each wagon.

Solution

Let's assume that the initial amount of coal in each wagon is x tons.

According to the problem, after unloading 12 tons from the first wagon, the first wagon is left with 6 times more coal than the second wagon. This can be expressed as:

x - 12 = 6(x - 22)

Simplifying the equation:

x - 12 = 6x - 132

-5x = -120

x = 24

Therefore, the initial amount of coal in each wagon was 24 tons.

Answer

The initial amount of coal in each wagon was 24 tons.
