Question

На одній автостоянці було в 3 рази (-ів) менше машин, ніж на іншій. Коли з другої стоянки на першу перевели 36 автомобілі (-ів), машин на стоянках стало порівну. Скільки машин було на кожній стоянці спочатку?

Answer 1

Ответ:

48 и 144 автомобиля

Пошаговое объяснение:

x - на первой,

3x - на второй,

3x - 48 = x + 48

2x = 48 + 48

2x = 96

x = 48 (а)

48 * 3 = 144(а)

Answer 2

Initial Situation

The initial situation describes two parking lots, one of which had three times fewer cars than the other.

Mathematical Representation

Let's represent the number of cars on the first parking lot as x and the number of cars on the second parking lot as 3x (three times more).

Transfer of Cars

When 36 cars were transferred from the second parking lot to the first, the number of cars became equal on both parking lots.

Equation Setup

We can set up the equation to represent this situation: The number of cars on the first parking lot after the transfer: x + 36 The number of cars on the second parking lot after the transfer: 3x - 36

Equation to Solve

Setting these two expressions equal to each other gives us the equation: x + 36 = 3x - 36

Solving for x

Solving for x: x = 36 + 36 = 72

Calculating the Initial Numbers

So, initially, there were 72 cars on the first parking lot and 3 * 72 = 216 cars on the second parking lot.
