Question

В саду яблонь было в 3 раза больше, чем груш. После того, как 14 яблонь вырубили и посадили 10 груш, деревьев обоих видов в саду стало поровну. Сколько яблонь и сколько груш было в саду первоначально​

Answer 1

Пошаговое объяснение:

Пусть х груш

3х яблонь

3х-14=х+10

3х-х=10+14

2х=24

Х=12 груш

3×12=36 яблонь

Answer 2

Ответ:

Пошаговое объяснение:

было груш - х (дер.)

было яблонь - 3х (дер.)

Стало груш  - х + 10 (д.)

Стало яблонь - 3х - 14

х + 10 = 3х - 14 по условию

3х - х = 10 + 14

2х = 24

х = 24/2 = 12 (д.) - было груш

12 * 3 = 36(д.) - было яблонь

Проверка:

12 + 10 = 3*12 - 14

22 = 36 -14 = 22

Ответ: было груш -12д., яблонь - 36 деревьев

Problem Analysis

We are given the information that initially, there were three times as many apple trees as pear trees in a garden. After 14 apple trees were cut down and 10 pear trees were planted, the number of both types of trees became equal. We need to determine the initial number of apple trees and pear trees in the garden.

Solution

Let's assume the initial number of pear trees in the garden is x. According to the given information, the initial number of apple trees is three times the number of pear trees, which is 3x.

After 14 apple trees were cut down, the number of apple trees became 3x - 14. Similarly, after 10 pear trees were planted, the number of pear trees became x + 10.

According to the problem, the number of apple trees and pear trees became equal after these changes. Therefore, we can set up the following equation:

3x - 14 = x + 10

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

3x - 14 = x + 10

Subtract x from both sides:

2x - 14 = 10

Add 14 to both sides:

2x = 24

Divide both sides by 2:

x = 12

So, the initial number of pear trees in the garden was 12.

Since the initial number of apple trees was three times the number of pear trees, the initial number of apple trees in the garden was 3 * 12 = 36.

Therefore, there were initially 36 apple trees and 12 pear trees in the garden.

Answer

The initial number of apple trees in the garden was 36, and the initial number of pear trees was 12.

Answer 4

Я попробую ответить на ваш вопрос. В саду яблонь было в 3 раза больше, чем груш. Пусть x - количество груш в саду первоначально, тогда количество яблонь было 3x. После того, как 14 яблонь вырубили и посадили 10 груш, деревьев обоих видов в саду стало поровну. То есть, 3x - 14 = x + 10. Решая это уравнение, получаем x = 12. Значит, в саду первоначально было 12 груш и 36 яблонь. Надеюсь, это поможет вам.
