Question

-0,66x+(9-13)=8+9-2,66x​

Answer 1

$-0,66x+(9-13)=8+9-2,66x\\\\-0,66x-4=17-2,66x\\\\2,66x-0,66x=17+4\\\\2x=21\\\\x=\dfrac{21}{2}\\\\x=10,5$

Answer 2

Ответ:

-0,66x+(-4)=8+9-2,66x

-0,66x-4=17-2,66x

-0,66x+2,66x=17+4

2x=17+4

2x=21

2x=21/2

x= 21/2

Answer 3

To solve this equation for the variable x, follow these steps:

1. Start by simplifying both sides of the equation by performing the operations within the parentheses:

   -0.66x + (9 - 13) = 8 + 9 - 2.66x

   -0.66x + (-4) = 17 - 2.66x

2. Next, combine like terms on both sides of the equation. Add 2.66x to both sides to get the x terms on one side:

   -0.66x + 2.66x - 4 = 17

3. Now, simplify the x terms on the left side:

   (2.66x - 0.66x) - 4 = 17

   2x - 4 = 17

4. Add 4 to both sides of the equation to isolate the 2x term:

   2x - 4 + 4 = 17 + 4

   2x = 21

5. Finally, divide both sides by 2 to solve for x:

   2x / 2 = 21 / 2

   x = 21 / 2

So, the solution to the equation is:

x = 10.5
