| **The mass of two baguettes is 20kg, and the mass of one of them is 3 times less than the mass of the other, find the mass of each baguette**

Let the mass of the first suitcase be x kg. If the first suitcase weighs 3 times less than the other, then the other is three times heavier than the first, and then the mass of the second is 3x kg.

Let’s find how much each suitcase weighs if their total mass is 20 kg.

We write the equation as the addition of the mass of two suitcases.

x kg + 3x kg = 20 kg.

4x kg = 20 kg.

x kg = 20 kg: 4;

x kg = 5 kg – weight of the first suitcase.

3 × 5 kg = 15 kg – the mass of the second suitcase.

Answer: the weight of the second suitcase is 15 kg, and the first one is 5 kg.
