Answer 1

Ответ:

14

Пошаговое объяснение:

Пусть x — количество учеников, которые пришли.

Тогда: 31 = 17 + x, отсюда

x = 31 - 17

x = 14

Answer 2

Solving for the Number of Students

To solve for the number of students who arrived in the room, we can use the given information that there were initially 17 students in the room, and after a few more students arrived, the total number became 31. Let's denote the number of students who arrived as x.

We can set up the following equation to represent the situation: 17 + x = 31

Now, let's solve for x:

17 + x = 31 x = 31 - 17 x = 14

So, 14 students arrived in the room.

Conclusion

The number of students who arrived in the room is 14.
