Question

Задача : В трех вогонах поезда едут 100 пассажиров. в первом и втором вогонах вместе 66 пассажиров, а во втором и третьем вагонах вместе 69 пассажиров. сколько пассажиров в каждом вагоне? плиззз

Answer 1

100 - 66 = 34 (п) в третьем вагоне
100 - 69 = 31 (п) в первом вагоне
34 + 31 = 65 (п) во втором вагоне

Answer 2

В первом - 31
Во втором - 35
В третьем - 34

Answer 3

Problem:

The problem states that there are three train cars, and a total of 100 passengers are traveling in them. The first and second cars together have 66 passengers, while the second and third cars together have 69 passengers. We need to determine how many passengers are in each car.

Solution:

Let's assume that the number of passengers in the first car is x, the number of passengers in the second car is y, and the number of passengers in the third car is z.

From the given information, we can form the following equations:

1. Equation 1: x + y = 66 (The first and second cars together have 66 passengers) 2. Equation 2: y + z = 69 (The second and third cars together have 69 passengers) 3. Equation 3: x + y + z = 100 (The total number of passengers in all three cars is 100)

To solve these equations, we can use a method called substitution. We'll solve Equation 1 for x and substitute it into Equations 2 and 3.

From Equation 1, we have: x = 66 - y

Substituting this value of x into Equations 2 and 3, we get:

Equation 2: (66 - y) + y + z = 69 Equation 3: (66 - y) + y + z = 100

Simplifying Equation 2, we get: 66 + z = 69 - y Simplifying Equation 3, we get: 66 + z = 100 - y

Now, we have two equations with two variables (y and z). We can solve these equations simultaneously to find the values of y and z.

Let's solve the equations:

Equation 2: 66 + z = 69 - y Equation 3: 66 + z = 100 - y

By subtracting Equation 2 from Equation 3, we can eliminate z:

(66 + z) - (66 + z) = (100 - y) - (69 - y) 0 = 31

This equation is not possible, as it implies 0 = 31, which is false. Therefore, there is no solution that satisfies all the given conditions.
