Question

первом ряду кустов смородины в 3раза больше чем во втором. Если с первого ряда пересадить 12 кустов на второй, то количество кустов смородины в каждом ряду станет одинаковым. Сколько кустов смородины было во втором ряду первоначально? [4балла] ​

Answer 1

Ответ: в первом ряду 36, во втором 12.

Пошаговое объяснение: первый ряд -3х, второй 1х. 3х-12=1х+12. 3х-1х=2х. 3х-1х=24. 24:2=12. 1х=12.

Answer 2

Task Analysis

The problem involves determining the initial number of currant bushes in the second row, given that there are three times as many currant bushes in the first row as in the second row, and if 12 bushes are transplanted from the first row to the second row, the number of bushes in each row becomes equal.

Solution

Let's denote the initial number of currant bushes in the second row as x. Given that the number of currant bushes in the first row is three times the number in the second row, the initial number of currant bushes in the first row is 3x. When 12 bushes are transplanted from the first row to the second row, the number of bushes in each row becomes equal. This can be represented by the equation: 3x - 12 = x + 12

Calculation

Solving the equation: 3x - 12 = x + 12 2x = 24 x = 12

So, the initial number of currant bushes in the second row was 12.

Therefore, the initial number of currant bushes in the second row was 12.
