Answer 2

Ответ:

-0,5

Пошаговое объяснение:

0,3(2х – 1) = 0,8 +0,2(10х - 2)

0,6x - 0,3 = 0,8 + 2x - 0,4

0,6x - 2x = 0,4 + 0,3

-1,4x = 0,7

x = -0,5

Answer 3

To solve the equation, we can follow these steps:

1. Distribute the constants on both sides of the equation.
2. Distribute the variables on both sides of the equation.
3. Simplify and solve for x.

Let's go through these steps:

Given equation: 0.3(2x - 1) = 0.8 + 0.2(10x - 2)

Step 1: 0.3 * 2x - 0.3 * 1 = 0.8 + 0.2 * 10x - 0.2 * 2 0.6x - 0.3 = 0.8 + 2x - 0.4

Step 2: Combine like terms on both sides of the equation: 0.6x - 2x = 0.8 - 0.3 + 0.4 - 0.3 -1.4x = 0.9

Step 3: Divide both sides by -1.4: x = 0.9 / -1.4 x = -0.642857...

So, the solution to the equation is approximately x = -0.642857...
