Question

В двух грузовых вагонах было поровну угля. когда из первого вагона выгрузили 12 т угля, из второго - 22 т, то в первом вагоне осталость в 6 раз больше угля, чем во втором. сколько тонн угля было в каждом вагоне вначале?

Answer 1

Я решу уравнением 
x-12 = (x-22) * 6 
x-12 = 6x-132
120=5x
x=24 

Answer 2

Problem Analysis

We are given that there was an equal amount of coal in two freight cars. When 12 tons of coal were unloaded from the first car and 22 tons were unloaded from the second car, the first car ended up with 6 times more coal than the second car. We need to determine how many tons of coal were initially in each car.

Solution

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

According to the given information, when 12 tons of coal were unloaded from the first car and 22 tons were unloaded from the second car, the first car ended up with 6 times more coal than the second car. This can be expressed as:

x - 12 = 6(x - 22)

Simplifying the equation:

x - 12 = 6x - 132

-5x = -120

x = 24

Therefore, there were initially 24 tons of coal in each car.

Answer

There were initially 24 tons of coal in each freight car.
