Question

2,5 - 2х = х - 3,8 • (-5)

Answer 1

Ответ:

Пошаговое объяснение:

2,5 - 2х = х - 3,8 • (-5)

2.5-2х=х+19

-2х-х=19-2.5

-3х=16.5

х=16.5:(-3)

х=-5.5

Answer 2

2.5 - 2x = x - 3.8 * (-5)

-2x - x = 19 - 2.5

-3x = 16.5

x = -5.5

Answer 3

To solve the equation 2.5 - 2x = x - 3.8 * (-5), we can follow these steps:

1. Distribute the multiplication on the right side: 2.5 - 2x = x + 19

2. Combine like terms by moving the x term to one side: -2x - x = 19 - 2.5

Simplifying further: -3x = 16.5

3. Divide both sides of the equation by -3 to solve for x: x = 16.5 / -3

Evaluating the division: x = -5.5

Therefore, the solution to the equation 2.5 - 2x = x - 3.8 * (-5) is x = -5.5.
