15 +8х = 2х – 21

8х-2х=-21-15

6х=-36

х=-36:6

х=-6

Answer 2

Ответ: -6

Пошаговое объяснение:

8x -2x = -21 -15

6x = -36

x = -6

Answer 3

To solve the equation for х:

15 + 8х = 2х - 21

First, let's simplify the equation by subtracting 2х from both sides:

15 + 8х - 2х = -21

Combine the like terms:

6х + 15 = -21

Now, subtract 15 from both sides:

6х = -36

Finally, divide both sides by 6 to solve for х:

х = -36 / 6

х = -6

So, the solution for the equation is х = -6.
