Question

На левой чаше три пакетика с мукой, а на правой 1 пакет Муки и Две гири массой по 2 килограмма составьте по рисунку и линейного уравнения Где масса одного пакета муки равна Решите уравнение и Найдите массу одного пакета муки

Answer 1

3х=х+4
3х-х=4
2х=4
х=4:2
х=2
3*3=2+4
пакет с мукой весит 2 кг

Answer 2

Setting up the Problem

On the left side of the scale, there are three packets of flour, and on the right side, there is one packet of flour and two weights weighing 2 kilograms each. We need to set up a linear equation to represent this situation and find the mass of one packet of flour.

Let's assume the mass of one packet of flour is x kilograms.

Writing the Equation

To balance the scale, the total mass on the left side should be equal to the total mass on the right side.

The total mass on the left side is the sum of the masses of the three packets of flour, which is 3x kilograms.

The total mass on the right side is the mass of one packet of flour plus the sum of the masses of the two weights, which is x + 2 + 2 = x + 4 kilograms.

Therefore, the equation representing the balance of the scale is:

3x = x + 4

Solving the Equation

To solve the equation, we'll simplify and isolate the variable x.

Subtract x from both sides of the equation:

3x - x = x + 4 - x

Simplifying:

2x = 4

Divide both sides of the equation by 2:

x = 2

Finding the Mass of One Packet of Flour

The mass of one packet of flour is 2 kilograms.
