Question

3х-(6х-(9х-(2х-5)))=1​

Answer 1

Ответ:

-1

Пошаговое объяснение:

3х - (6х - (9х - 2х + 5) ) = 1

3х - (6х - 9х + 2х - 5) = 1

3х - 6х + 9х - 2х + 5 = 1

3х - 6х + 9х - 2х = 1 - 5

4х = -4

х = -4 : 4

х = -1

Ответ: -1

Answer 2

Ответ:

х = -1

Пошаговое объяснение:

Последовательно справа налево раскрываем каждую скобку и не забываем, если перед скобкой стоит знак "-",  меняем знаки слагаемых или вычитаемых, которые стояли в скобках, на противоположные (знак "-" меняется на "+", знак "+" на "-")

3х - (((6х - (9х - (2х - 5))) = 1​

3х - ((6х - (9х - 2х + 5)) = 1​

3х - ((6х - (7х + 5)) = 1​

3х - (6х - 7х - 5) = 1​

3х - (-х - 5) = 1

3х + х + 5 = 1

4х = 1 - 5

4х = -4

х = -4/4

х = -1

Answer 3

Let's simplify the expression step by step:

1. Start with the innermost parentheses:

   9x - (2x - 5)

   First, distribute the negative sign inside the inner parentheses:

   9x - 2x + 5

   Now combine like terms:

   7x + 5

2. Now, we have the expression:

   3x - (6x - (7x + 5))

   Again, distribute the negative sign inside the second set of parentheses:

   3x - 6x + (7x + 5)

   Combine like terms:

   3x - 6x + 7x + 5

   Now, combine the x-terms:

   (3x - 6x + 7x) + 5

   • (3x) + 5

   -3x + 5

3. Finally, the expression is:

   -3x + 5 = 1

Now, let's solve for x:

Subtract 5 from both sides:

-3x = 1 - 5

-3x = -4

Now, divide by -3 to solve for x:

x = (-4) / (-3)

x = 4/3

So, the solution for the equation 3x - (6x - (9x - (2x - 5))) = 1 is x = 4/3.
