Пошаговое объяснение:

Решение:

$12-15x+10=28-4x-8x\\22-15x=28-12x\\22-3x=28\\3x=22-28\\3x=(-6)\\x=(-6):3\\x=(-2)$

Answer 3

To solve for the value of x in the equation 12 - 15x + 10 = 28 - 4x - 8x, follow these steps:

1. Combine like terms on both sides of the equation: Combine the constants on the left side: 12 + 10 = 22 Combine the x terms on the right side: -4x - 8x = -12x

   The equation becomes: 22 - 15x = 28 - 12x

2. Subtract 22 from both sides of the equation to isolate the x terms on one side: 22 - 15x - 22 = 28 - 12x - 22 -15x = 6 - 12x

3. Add 12x to both sides of the equation to collect the x terms on one side: -15x + 12x = 6 - 12x + 12x -3x = 6

4. Finally, divide both sides by -3 to solve for x: x = 6 / -3 x = -2

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