Answer 1

Ответ:

2х-3.6-3.8х= 1.8-1.8х+ 5.4

2х-3.8х+1.8х=1.8+5.4+3.6

х=10.8

Answer 2

Ответ:

Бесконечное множество корней.

Пошаговое объяснение:

0,4(5x-9)-3.8x = 1.8-1.8(x+3)

2x-3.6-3.8x = 1.8-1.8x-5.4

2x-3.8x+1.8x = 1.8-5.4+3.6

0 = 0

Answer 3

To solve the equation 0.4(5x - 9) - 3.8x = 1.8 - 1.8(x + 3), we will simplify and solve for x. Let's break down the steps:

0.4(5x - 9) - 3.8x = 1.8 - 1.8(x + 3)

First, distribute the 0.4 and 1.8:

2x - 3.6 - 3.8x = 1.8 - 1.8x - 5.4

Combine like terms:

2x - 3.8x - 1.8x = 1.8 - 3.6 - 5.4 + 3.6

Simplify:

-3.6x = -3.6

Next, divide both sides of the equation by -3.6 to solve for x:

-3.6x / -3.6 = -3.6 / -3.6

Simplifying further:

x = 1

Therefore, the solution to the equation 0.4(5x - 9) - 3.8x = 1.8 - 1.8(x + 3) is x = 1.
