Question

На автомобильной стоянке было в 4 раза меньше машин чем на другой Когда со второй стоянки на первую перевели 12 автомобилей машин на стоянке стало поровну Сколько машин было на каждой стоянке первоначально

Answer 1

Пусть Х машин было на первой стоянке, тогда 4Х машин было на другой стоянке. Выразим, сколько машин стало на каждой стоянке
Х+12=4Х-12
3Х=24
Х=8 машин было на первой стоянке
4Х=4*8=32 машин было на другой стоянке

Answer 2

Problem Analysis

We are given two parking lots, and initially, the number of cars in one parking lot is four times less than the number of cars in the other parking lot. Later, 12 cars are transferred from the second parking lot to the first parking lot, resulting in an equal number of cars in both parking lots. We need to determine the initial number of cars in each parking lot.

Solution

Let's assume the initial number of cars in the first parking lot is x. According to the problem, the initial number of cars in the second parking lot is four times greater than the first parking lot, so it is 4x.

After transferring 12 cars from the second parking lot to the first parking lot, the number of cars becomes equal in both parking lots. Therefore, we can set up the following equation:

x + 12 = 4x

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

Solving the Equation

To solve the equation, we'll isolate x on one side:

x + 12 = 4x

Subtract x from both sides:

12 = 3x

Divide both sides by 3:

x = 4

Answer

The initial number of cars in the first parking lot was 4, and the initial number of cars in the second parking lot was 4 * 4 = 16.

Therefore, initially, there were 4 cars in the first parking lot and 16 cars in the second parking lot.
