Answer 1

2 коробки по 7кг и 4коробки по 4кг так получается поровну

Answer 2

Calculation of the Number of Boxes

To determine the number of boxes weighing 7 kg, we need to divide the total weight of the strawberry harvest, which is 30 kg, by the sum of the weights of the two types of boxes, 7 kg and 4 kg.

Let's denote the number of boxes weighing 7 kg as x. The number of boxes weighing 4 kg can be calculated by subtracting x from the total number of boxes, which is 6.

To find x, we can set up the following equation:

7x + 4(6 - x) = 30

Simplifying the equation:

7x + 24 - 4x = 30

Combining like terms:

3x + 24 = 30

Subtracting 24 from both sides:

3x = 6

Dividing both sides by 3:

x = 2

Therefore, there were 2 boxes weighing 7 kg.
