Question

-0,3(8-4x)=0,6(x-3)+0,9

Answer 1

Ответ:

х=2,5.

Пошаговое объяснение:

-0,3(8-4x)=0,6(x-3)+0,9;

-2,4+1,2х=0,6х-1,8+0,9;

1,2х-0,6х=2,4-1,8+0,9;

0,6х=1,5;

х=2,5.

Answer 2

-0,3(8-4x)=0,6(x-3)+0,9

-2,4+1,2x=0,6x-1,8+0,9

-2,4+1,2x=0,6x-0,9

1,2x-0,6x=-0,9+2,4

0,6x=1,5

x=2,5

Answer 3

To solve the equation -0.3(8-4x) = 0.6(x-3) + 0.9, we will start by simplifying and then isolating the variable.

Let's simplify the equation step by step:

-0.3(8-4x) = 0.6(x-3) + 0.9

Distribute the -0.3 on the left side:

-0.3 * 8 + 0.3 * 4x = 0.6(x-3) + 0.9

-2.4 + 1.2x = 0.6(x-3) + 0.9

Next, distribute the 0.6 on the right side:

-2.4 + 1.2x = 0.6x - 1.8 + 0.9

Combine like terms:

1.2x - 2.4 = 0.6x - 0.9

Now, let's isolate the variable x by moving all the x terms to one side and the constant terms to the other side:

1.2x - 0.6x = -0.9 + 2.4

0.6x = 1.5

Divide both sides by 0.6 to solve for x:

x = 1.5 / 0.6

x ≈ 2.5

Therefore, the solution to the equation is x ≈ 2.5.
