The total weight of two cases of apples is 20 kg. If 4 / 1 kg is taken out of the first case and put into the second case, the two cases of apples will have the same weight? Please

The difference between the original two cases: 1 / 4 × 2 = 1 / 2kg
Original weight of the first item: (20-1 / 2) △ 2 + 1 / 2 = 10.25 (kg)
