Question

1.3-3.6(x-3)=5(8-0.4x)

Answer 1

1.3-3.6(x-3)=5(8-0.4x)

1.3-3,6х+10,8=40-2х

12.1-3,6х=40-2х

-3.6х+2х=40-12,1

-1,6х=27,9

х=-17, 4375

Answer 2

Ответ:

x= -17.94

Пошаговое объяснение:

1.3 - 3.6(x-3) = 5(8-0.4x)

1.3 - 3.6x +10.8=40 - 2x

-3.6x+2x=40-10-1.3

-1.6x = 28.7

x= -17.94

Answer 3

To solve the equation 1.3-3.6(x-3)=5(8-0.4x), we'll simplify and then isolate the variable x. Let's go step by step:

1. Distribute the terms on both sides of the equation: 1.3 - 3.6(x) + 3 = 40 - 5(0.4x)

2. Simplify: 1.3 - 3.6x + 3 = 40 - 2x

3. Combine like terms: 4.3 - 3.6x = 40 - 2x

4. Move all the terms with x to one side and the constant terms to the other side. Let's subtract 40 from both sides and add 3.6x to both sides: 4.3 - 40 = 3.6x - 2x

   -35.7 = 1.6x

5. Divide both sides of the equation by 1.6 to solve for x: -35.7 / 1.6 = x

   x ≈ -22.31

Therefore, the solution to the equation 1.3-3.6(x-3)=5(8-0.4x) is approximately x = -22.31.
