Answer 1

Было х, тогда 
х-6+19 = 50
х=50-19+6
х=37

Answer 2

Я думаю

50-19=31

31+6=37 вагонов было первоначально

Answer 3

Calculating the Initial Number of Wagons in the Train Composition

To calculate the initial number of wagons in the train composition, we can use the information provided: 6 wagons were detached from the freight train, and then 19 wagons were attached to it, resulting in a total of 50 wagons.

Let's denote the initial number of wagons as x.

The equation representing the given scenario is: x - 6 + 19 = 50

Solving for x: x + 13 = 50 x = 50 - 13 x = 37

So, the initial number of wagons in the train composition was 37.

Conclusion

The initial number of wagons in the train composition was 37.
