Question

0,3(2х - 1) -0,9 = 0,2(5х-2)

Answer 1

0,6х-0,3-0,9=х-0,4

0,6х-1,2=х-0,4

0,6х-х=-0,4+1,2

-0,4х=0,8

Х=-2

Answer 2

To solve the equation 0.3(2x - 1) - 0.9 = 0.2(5x - 2), we can follow these steps:

Step 1: Distribute the values inside the parentheses: 0.6x - 0.3 - 0.9 = x - 0.4

Step 2: Combine like terms on both sides of the equation: 0.6x - 1.2 = x - 0.4

Step 3: Move all the terms with x to one side of the equation by subtracting x from both sides: 0.6x - x - 1.2 = -0.4

Simplifying, we get: -0.4x - 1.2 = -0.4

Step 4: Move the constant term to the other side by adding 1.2 to both sides: -0.4x - 1.2 + 1.2 = -0.4 + 1.2

Simplifying, we get: -0.4x = 0.8

Step 5: Divide both sides of the equation by -0.4 to solve for x: (-0.4x) / (-0.4) = 0.8 / (-0.4)

Simplifying, we get: x = -2

Therefore, the solution to the equation is x = -2.
