Question

0,3(2x-1)-0,9=0,2(5x-2)​

Answer 1

Ответ:

-2

Пошаговое объяснение:

0,3(2x-1)-0,9=0,2(5x-2)

0,6x-0,3-0,9=x-0,4

-0,4x=0,8

x=-2

Answer 2

0,3(2x-1)-0,9=0,2(5x-2)

0,6х-0,3-0,9=х-0,4

0,6х-х=-0,4+0,3+0,9

-0,4х=0,8

х=-2

Answer 3

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

Step 1: Distribute the coefficients on both sides of the equation.

0.3 * 2x - 0.3 * 1 - 0.9 = 0.2 * 5x - 0.2 * 2

Step 2: Simplify each side by performing the operations.

0.6x - 0.3 - 0.9 = x - 0.4

Step 3: Combine like terms.

0.6x - 1.2 = x - 0.4

Step 4: Move all terms involving x to one side of the equation.

0.6x - x = -0.4 + 1.2

Step 5: Simplify and solve for x.

0.6x - x = 0.8

0.6x - 1x = 0.8

-0.4x = 0.8

x = 0.8 / -0.4

x = -2

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