Question

8,5x – 2,15x = 3,05x + 8,91

Answer 1

Ответ:

х = 27

Пошаговое объяснение:

8,5x - 2,15x = 3,05x + 8,91

8,5x - 2,15x - 3,05х = 8,91

3,3х = 8,91

х = 8,91/3,3

х = 27

Answer 2

To solve the equation 8.5x - 2.15x = 3.05x + 8.91, you'll want to isolate the variable x. Here are the steps to do that:

1. First, combine like terms on both sides of the equation.

On the left side, you have 8.5x - 2.15x, which equals 6.35x. On the right side, you have 3.05x + 8.91 as it is.

So, the equation becomes:

6.35x = 3.05x + 8.91

2. Next, you want to get all the terms with x on one side of the equation and the constants on the other side. To do that, you can subtract 3.05x from both sides of the equation:

6.35x - 3.05x = 3.05x - 3.05x + 8.91

This simplifies to:

3.3x = 8.91

3. Finally, to solve for x, divide both sides of the equation by 3.3:

(3.3x)/3.3 = 8.91/3.3

x = 2.7

So, the solution to the equation is x = 2.7.
