Пошаговое объяснение:

Раскрываем скобки:

280-12х=35,5-10,5-3х

Все неизвестные - в одну сторону:

12х-3х=280-35,5+10,5

9х=255, х= 28 целых и 1/3

Answer 2

To solve the equation 8(35 - 1.5x) = 35.5 - 1.5(7 + 2x), you can follow these steps:

1. Distribute the 8 on the left side and the -1.5 on the right side of the equation:

   8 * 35 - 8 * 1.5x = 35.5 - 1.5 * 7 - 1.5 * 2x

2. Simplify each side of the equation:

   280 - 12x = 35.5 - 10.5 - 3x

3. Next, you can gather like terms by adding 12x to both sides of the equation and subtracting 35.5 from both sides:

   280 - 35.5 - 12x + 12x = -10.5 - 3x + 12x

   244.5 = 8.5x

4. Finally, divide both sides by 8.5 to solve for x:

   (244.5) / 8.5 = (8.5x) / 8.5

   x ≈ 28.76

So, the solution to the equation is approximately x ≈ 28.76.
