Весь багаж 32кг 1 ?кг  2 ?кг на 9 кг меньше 1 3 ?кг на 7 кг меньше1 Пусть вес первого чемодана будет х, тогда вес 2го (х-9)кг, вес третьего (х-7)кг Уравнение х+х-9+х-7=32 3х-16=32 х=16кг-вес первого, самого тяжелого багажа

Answer 2

Calculating the Weight of the Heaviest Suitcase

To calculate the weight of the heaviest suitcase, we can use the information provided about the weight differences between the suitcases.

The first suitcase is 9 kg heavier than the second suitcase and 7 kg heavier than the third suitcase. This means that the difference in weight between the first and third suitcases is 9 kg - 7 kg = 2 kg.

Given that the total weight of all three suitcases is 32 kg, we can set up the following equation to find the weight of the heaviest suitcase:

Let's assume the weight of the third suitcase is x kg. Then, the weight of the first suitcase would be x + 7 kg.

The total weight equation can be expressed as: x + (x + 7) + (x + 9) = 32

Solving for x: 3x + 16 = 32 3x = 16 x = 16 / 3 x = 5.33

So, the weight of the third suitcase is approximately 5.33 kg.

Therefore, the weight of the heaviest suitcase is 5.33 kg + 9 kg = 14.33 kg.

This calculation shows that the heaviest suitcase in the baggage weighs approximately 14.33 kg.
