Question

В одном зале кинотеатра в 2 раза больше зрителей+чем в другом.Естли из первого зала уйдут 37 человек,а во второй зал придут 50,то зрителей в обоих залах будет поровну.Сколько зрителей в каждом зале??ПОЖАЛУЙСТА РЕШИТЕ ОЧЕНЬ НАДО!!!!!!!!!

Answer 1

Пусть в 1 зале  -Х зрителей

Тогда во 2 зале 2Х зр

Когда из  второго зала ушли 37 зр, то стало 2Х-37  зр.

Когда в первый зал пришли 50 зр., то стало Х+50  зр.

После этого зрителей  в залах стало поровну

Можем составить уавнение

Х+50=2Х-37

Х=50+37

Х=87

Ответ в 1 зале-87 зр.

          во 2 зале 87 х2 =174зр

Проверка

87+50=2 х 87 -37

    137=137 Верно

 

 

Answer 2

Problem Analysis

We are given that there are twice as many spectators in one cinema hall as in another. If 37 people leave the first hall and 50 people enter the second hall, the number of spectators in both halls will be equal. We need to find the number of spectators in each hall.

Solution

Let's assume the number of spectators in the first hall is x. According to the given information, the number of spectators in the second hall is twice that of the first hall, which means it is 2x.

When 37 people leave the first hall, the number of spectators in the first hall becomes x - 37. Similarly, when 50 people enter the second hall, the number of spectators in the second hall becomes 2x + 50.

According to the problem, the number of spectators in both halls will be equal after these changes. Therefore, we can set up the following equation:

x - 37 = 2x + 50

Now, let's solve this equation to find the value of x.

x - 37 = 2x + 50

x - 2x = 50 + 37

-x = 87

x = -87

Since we cannot have a negative number of spectators, it seems there might be an error in the problem statement or the given information. Please double-check the problem statement and provide any additional information if available.
