Question

4x+2*(1,2-3x) =1,8-2*(x*0,3)​

Answer 1

4x+2*(1,2-3x) =1,8-2*(x*0,3)​

х+2,4-6х=1,8-1,2х

х+1,2х-6х=-0,6

х= -0,6 / -3,8

х=1,6

Answer 2

Ответ:

4x+2*(1,2-3x) =1,8-2*(x*0,3)​

4x+2.4-6х=1.8-2*(0.3х)

-2х+2.4=1.8-2*0.3х

-2х+2.4=1.8-0.6х

-2х+0.6х=1.8-2.4

-1.4х=-0.6

х=$\frac{3}{7}$

Answer 3

To solve the equation 4x + 2 * (1.2 - 3x) = 1.8 - 2 * (x * 0.3), we can follow these steps:

1. Distribute the multiplication: 4x + 2 * 1.2 - 2 * 3x = 1.8 - 2 * (x * 0.3)

   Simplifying, we have: 4x + 2.4 - 6x = 1.8 - 0.6x

2. Combine like terms on both sides of the equation: (4x - 6x) + 2.4 = 1.8 - 0.6x

   Simplifying, we have: -2x + 2.4 = 1.8 - 0.6x

3. Move all terms with x to one side of the equation: -2x + 0.6x = 1.8 - 2.4

   Simplifying, we have: -1.4x = -0.6

4. Divide both sides of the equation by -1.4 to isolate x: x = (-0.6) / (-1.4)

   Simplifying, we get: x ≈ 0.4286

Therefore, the approximate solution for the equation 4x + 2 * (1.2 - 3x) = 1.8 - 2 * (x * 0.3) is x ≈ 0.4286.
