0,6x + 1,2 - 1,2x + 1,8 = 4x - 20

-0.6x + 3 = 4x - 20

-0,6x - 4x = -20 -3

-4,6x = -23

x=5

Answer 2

Ответ:

0.6(х+2)-0,2(6х-9)=4х-20

0,6х+1,2-1,2х+1,8=4х-20

0,6х-1,2х-4х=-20-1,8-1,2

-4,6х=-23

Х=23:4,6

Х=5

Answer 3

To solve the equation 0.6(x + 2) - 0.2(6x - 9) = 4x - 20, follow these steps:

Step 1: Distribute the constants and variables on both sides of the equation:

0.6x + 0.62 - 0.26x + 0.2*9 = 4x - 20

Step 2: Perform the multiplications:

0.6x + 1.2 - 1.2x + 1.8 = 4x - 20

Step 3: Combine like terms on both sides of the equation:

(0.6x - 1.2x) + (1.2 + 1.8) = 4x - 20

-0.6x + 3.0 = 4x - 20

Step 4: Move the variable terms (terms with x) to one side of the equation and constants to the other side:

-0.6x - 4x = -20 - 3.0

-4.6x = -23.0

Step 5: Divide both sides by the coefficient of x (-4.6) to solve for x:

x = (-23.0) / (-4.6)

x = 5

So, the solution to the equation is x = 5.
