Answer 1

1способ 
Пусть х - сколько осталось человек в автобусе, тогда:
х+5+11=49
х+16=49
х=49-16
х=33-осталось в автобусе

2 способ
5+11=16-вышли из автобуса
49-16=33 - остались в автобусе

Answer 2

1) 49-5-11=33 (человека) осталось в автобусе
2) 5+11=16 (человек) всего вышло из автобуса
    49-16=33 (человека) осталось в автобусе

Answer 3

Problem Statement

На первой остановке из автобуса вышли 5 человек, а на второй - 11 человек. В начале в автобусе было 49 человек. Сколько человек осталось в автобусе? Решите задачу двумя способами.

Solution 1: Subtraction

To solve this problem using subtraction, we can subtract the number of people who got off the bus from the initial number of people in the bus.

1. Number of people who got off at the first stop: 5 2. Number of people who got off at the second stop: 11 3. Initial number of people in the bus: 49

To find the number of people remaining in the bus, we subtract the number of people who got off at both stops from the initial number of people in the bus:

49 - 5 - 11 = 33

Therefore, there are 33 people remaining in the bus.

Solution 2: Addition and Subtraction

Another way to solve this problem is by using addition and subtraction.

1. Number of people who got off at the first stop: 5 2. Number of people who got off at the second stop: 11 3. Initial number of people in the bus: 49

To find the number of people remaining in the bus, we can add the number of people who got off at both stops to the negative value of the initial number of people in the bus:

(-49) + 5 + 11 = -33 + 11 = -22

Since we cannot have a negative number of people in the bus, we take the absolute value of the result:

| -22 | = 22

Therefore, there are 22 people remaining in the bus.

Conclusion

There are two ways to solve the problem. Using subtraction, we find that there are 33 people remaining in the bus. Using addition and subtraction, we find that there are 22 people remaining in the bus.
