Question

0,8-0,5(x+3)=2-0,2(x-6)​

Answer 1

Ответ:

Пошаговое объяснение:

0,8-0,5(x+3)=2-0,2(x-6)​

0,8 - 0,5x - 1,5 = 2 - 0,2x + 1,2

-0,7 - 0,5x = 3,2 - 0,2x

0,5x - 0,2x = -0,7 - 3,2

0,3x = -3,9

x = -3,9 : 0,3

x = -13

Answer 2

To solve the equation 0.8 - 0.5(x + 3) = 2 - 0.2(x - 6), you can follow these steps:

1. Distribute the constants on the left side and right side of the equation:

0.8 - 0.5x - 0.5(3) = 2 - 0.2x + 0.2(6)

2. Simplify both sides:

0.8 - 0.5x - 1.5 = 2 - 0.2x + 1.2

3. Combine like terms on each side:

-0.5x - 0.7 = 2 - 0.2x + 1.2

4. Move the terms involving x to one side of the equation and constants to the other side:

-0.5x + 0.2x = 2 - 1.2 + 0.7

-0.3x = 0.5

5. Now, divide both sides by -0.3 to solve for x:

x = 0.5 / (-0.3)

x ≈ -1.67

So, the solution to the equation is x ≈ -1.67.
