Question

0,2(5х – 2) = 0,3(2х – 1) – 0,9

Answer 1

Ответ:х=-2

Пошаговое объяснение:

0,2(5х – 2) = 0,3(2х – 1) – 0,9

х-0,4=0,6х-0,3-0,9

х-0,6х=-0,3-0,9+0,4

0,4х=-0,8

х=-2

Answer 2

Ответ:

x = - 2

Пошаговое объяснение:

с начала домножим всё уравнение на 10

2(5x - 2) = 3(2x - 1) - 9

за тем раскроем скобки

10x - 4 = 6x - 3 -9

перенесём всё, что с икс в право, а всё остальное влево:

10x - 6x = 4 - 3 -9

4x = -8

x = -8 : 4

x = -2

Answer 3

To solve the equation 0.2(5x - 2) = 0.3(2x - 1) - 0.9, follow these steps:

1. Distribute the constants on the right side of the equation:

   0.2(5x - 2) = 0.3(2x - 1) - 0.9

   1x - 0.4 = 0.6x - 0.3 - 0.9

2. Move like terms to opposite sides of the equation:

   1x - 0.6x = -0.3 - 0.9 + 0.4

   0.4x - 0.6x = -0.3 - 0.9 + 0.4

   -0.2x = -0.8

3. Now, solve for x by dividing both sides by -0.2:

   (-0.2x) / (-0.2) = (-0.8) / (-0.2)

   x = 4

So, the solution to the equation is x = 4.
