Question

-(-3x)-(-(8-5x))=2(4-x)​

Answer 1

- (- 3x) - ( - (8 - 5x)) = 2(4 - x)

3x - (- 8 + 5x) = 8 - 2x

3x + 8 - 5x = 8 - 2x

- 2x + 8 = - 2x + 8

Ответ : x ∈ R

Answer 2

3х + 8 - 5х = 8 - 2х
3х - 5х + 2х = 8 - 8
0х = 0
Ответ: х-Любое число

Answer 3

Let's solve the equation step by step:

First, simplify the expressions within the parentheses:

-(-3x) = 3x -(8 - 5x) = -8 + 5x

Now, we can rewrite the equation with these simplifications:

3x - (-8 + 5x) = 2(4 - x)

Next, distribute the 2 on the right side of the equation:

3x - (-8 + 5x) = 8 - 2x

Now, let's simplify further:

3x + 8 - 5x = 8 - 2x

Now, combine like terms on both sides of the equation:

(3x - 5x) + 8 = 8 - 2x

-2x + 8 = 8 - 2x

Notice that the -2x terms on both sides of the equation cancel out. This means that the equation simplifies to:

8 = 8

This equation is always true, which means that it doesn't have a unique solution. In fact, any value of x will satisfy this equation because both sides are equal to 8. Therefore, this equation has infinitely many solutions, and it is an identity.
