Question

В двух бригадах было одинаковое количество рабочих После того как из первой бригады перевели во2 бригаду перевели 8 рабочих в ней стало в 3 раза меньше рабочих чем во второй бригаде сколько рабочих было в каждой бригаде

Answer 1

2. Пусть количество рабочих равно х, тогда
(x+8)/3 = x-8
3x-24=x+8
x=16
Ответ: 16 рабочих

Answer 2

Problem Analysis

We are given that there were an equal number of workers in two brigades. After transferring 8 workers from the first brigade to the second brigade, the number of workers in the second brigade became three times smaller than the number of workers in the first brigade. We need to determine the number of workers in each brigade before and after the transfer.

Solution

Let's assume the initial number of workers in each brigade is x. After transferring 8 workers from the first brigade to the second brigade, the number of workers in the second brigade becomes x - 8, and this is three times smaller than the number of workers in the first brigade.

We can write this as an equation: x - 8 = (1/3)x

To solve for x, we can multiply both sides of the equation by 3: 3(x - 8) = x

Expanding the equation: 3x - 24 = x

Simplifying the equation: 2x = 24

Dividing both sides of the equation by 2: x = 12

Therefore, the initial number of workers in each brigade was 12.

After transferring 8 workers from the first brigade to the second brigade, the number of workers in the second brigade becomes: x - 8 = 12 - 8 = 4

So, there were 12 workers in the first brigade and 4 workers in the second brigade after the transfer.

Answer

There were 12 workers in the first brigade and 4 workers in the second brigade.
