Question

2х – (4х – 5) = 5 – 2х.

Answer 1

Ответ:

x ∈ R

Пошаговое объяснение:

2x - (4x - 5) = 5 - 2x

2x - 4x + 5 = 5 - 2x

-2x + 5 = 5 - 2x

-2x + 2x = 5 - 5

0 = 0

Answer 2

Ответ:

х = 0

Пошаговое объяснение:

2х-(4х-5)=5-2х

2x-4x+5=5-2x

-2х+5=5-2х

-2х+2х=5-5

х=0

Answer 3

To solve the equation 2x - (4x - 5) = 5 - 2x, follow these steps:

Step 1: Distribute the negative sign through the parentheses: 2x - 4x + 5 = 5 - 2x

Step 2: Combine like terms on both sides of the equation: -2x + 5 = 5 - 2x

Step 3: Notice that we have -2x on both sides of the equation. This means that the -2x terms will cancel out when we subtract or add them from both sides. However, we need to be careful about the constant term (5) on the left side. Let's subtract 5 from both sides:

-2x + 5 - 5 = 5 - 2x - 5 -2x = -2x

At this point, the equation -2x = -2x indicates that the variable x can have any value. The equation is an identity, which means it's true for all values of x. This implies that there are infinitely many solutions for this equation, and any value of x will satisfy it.

In conclusion, the solution to the equation 2x - (4x - 5) = 5 - 2x is that it has infinitely many solutions, meaning that any real number can be a solution to this equation.
