Question

1,2 – 3,6( х – 3) = 5 ( 8 – 0,4х).

Answer 1

Ответ:

17.5

Пошаговое объяснение:

1.2-3.6х+10.8=40-2х

1.2+10.8-40=3.6х-2х

28=1.6х

Х=17.5

Answer 2

Ответ: 1.2-3.6х-10.8=40-2х

1.2-10,8-40=1.6х

49.6=1.6х

Х=49,6/1.6

Х=31

Answer 3

To solve the given equation, let's simplify and solve step by step:

1,2 - 3,6(х - 3) = 5(8 - 0,4х)

First, let's distribute the constants outside the parentheses:

1.2 - 3.6х + 10.8 = 40 - 0.4х

Combine like terms on both sides of the equation:

12 - 3.6х = 40 - 0.4х

Now, let's isolate the variable terms (terms with 'х') on one side of the equation:

-3.6х + 0.4х = 40 - 12

Simplify the coefficients of 'х':

-3.2х = 28

Finally, divide both sides by -3.2 to solve for 'х':

х = 28 / -3.2 х ≈ -8.75

So, the solution to the equation is approximately х = -8.75.
