Question

3,7-2,6(x-3)=5(8-0,2x)

Answer 1

Ответ:

-17,8125

Пошаговое объяснение:

Распределяем -2,6 и 5 через скобки: 3,7-2,6х+7,8=40-х

11,5-2,6х=40-х

Переносим неизвестные влево, а постоянные вправо и меняем знаки: -2,6х+х=40-11,5

Приводим подобные: -1,6х=28,5

х=-17,8125

Answer 2

To solve the equation 3,7-2,6(x-3)=5(8-0,2x), we can follow these steps:

1. Distribute the terms on both sides of the equation:

   3,7 - 2,6(x - 3) = 5(8 - 0,2x) 3,7 - 2,6x + 7,8 = 40 - 1x

2. Combine like terms:

   11,5 - 2,6x = 40 - x

3. Move all the terms containing x to one side of the equation and the constant terms to the other side:

   -2,6x + x = 40 - 11,5

   -1,6x = 28,5

4. Divide both sides of the equation by -1,6 to isolate x:

   x = 28,5 / -1,6

   x ≈ -17,8125

Therefore, the solution to the equation 3,7-2,6(x-3)=5(8-0,2x) is approximately x = -17,8125.
