Question

3. На одной клумбе было в 2 раза больше цветов, чем на другой. После того, как с первой клумбы пересадили 19 цветов, а на вторую досадили еще 21, на обоих клумбах цветов стало поровну. Сколько всего цветов было на двух клумбах изначально?​

Answer 1

Ответ:

Пошаговое объяснение:

первая клумба - 2х

вторая клумба - х

2х-19＝х+21

2х-х＝21+19

х＝40 - на второй клумбе цветов,

2х＝40*2＝80 - на первой клумбе,

40+80＝120 - всего цветов на двух клумбах изначально

Answer 2

Problem Analysis

We are given two flower beds, one with twice as many flowers as the other. After transplanting 19 flowers from the first flower bed and adding 21 more to the second flower bed, both flower beds have an equal number of flowers. We need to determine the total number of flowers on both flower beds initially.

Solution

Let's assume the number of flowers on the first flower bed is x. According to the problem, the second flower bed has twice as many flowers, so the number of flowers on the second flower bed is 2x.

After transplanting 19 flowers from the first flower bed, the number of flowers on the first flower bed becomes x - 19. After adding 21 flowers to the second flower bed, the number of flowers on the second flower bed becomes 2x + 21.

Since both flower beds have an equal number of flowers after these operations, we can set up the following equation:

x - 19 = 2x + 21

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

x - 19 = 2x + 21

x - 2x = 21 + 19

-x = 40

x = -40

Since the number of flowers cannot be negative, we can conclude that there is no solution to this problem. It is not possible for both flower beds to have an equal number of flowers after the given operations.

Therefore, we cannot determine the total number of flowers on both flower beds initially.

Answer

It is not possible to determine the total number of flowers on both flower beds initially.
