Question

824. 5) 2(x - 6) - х = 3х + 4х;​

Answer 1

Ответ:

2(x-6)-x=3x+4x

2x-12-x=3x+4x

X-12=7x

X-7x=12

-6x=12

X= - 2

Answer 2

Ответ:

х=-2

Пошаговое объяснение:

2(х-6)-х=3х-4х

2х-12-х=7х

х-12=7х

х-7х=12

-6х=12

х=-2

Answer 3

To solve the equation 2(x - 6) - x = 3x + 4x, follow these steps:

1. Distribute the 2 on the left side of the equation: 2(x - 6) - x = 3x + 4x becomes 2x - 12 - x = 3x + 4x.

2. Combine like terms on both sides of the equation. On the left side, combine 2x and -x, and on the right side, combine 3x and 4x: (2x - x) - 12 = (3x + 4x).

3. Simplify further: x - 12 = 7x.

4. Now, isolate the variable x by moving the 7x term to the other side of the equation. You can do this by subtracting 7x from both sides of the equation: x - 7x - 12 = 7x - 7x.

5. Simplify the equation: -6x - 12 = 0.

6. Finally, solve for x by adding 12 to both sides to isolate -6x: -6x - 12 + 12 = 0 + 12.

7. Simplify: -6x = 12.

8. To find x, divide both sides by -6: (-6x) / (-6) = 12 / (-6).

9. Simplify: x = -2.

So, the solution to the equation is x = -2.
