Question

-0,9(х-4)-3,3=0,6(2-х) решение

Answer 1

-0,9x+3.6-3.3=1.2-0.6x
-0.3x=0.9
x=-3

Answer 2

-0,9(х-4)-3,3=0,6(2-х)
-0,9x+3,6-3,3=1,2-0,6x
-0,9x+0,3=1,2-0,6x
-0,9x+0,6x=1,2-0,3
-0,3x=0,9
x=0,9/-0,3
x=-3

Ответ: -3

Answer 3

To solve the equation -0.9(x-4) - 3.3 = 0.6(2-x), follow these steps:

Step 1: Expand the brackets on both sides of the equation.

-0.9(x-4) - 3.3 = 0.6(2-x)

Multiply -0.9 with (x-4):

-0.9x + 0.94 - 3.3 = 0.6*(2-x)

Simplify:

-0.9x + 3.6 - 3.3 = 1.2 - 0.6x

Step 2: Combine like terms on both sides of the equation.

-0.9x + 0.3 = 1.2 - 0.6x

Step 3: Move all the terms with 'x' to one side of the equation and the constant terms to the other side.

-0.9x + 0.6x = 1.2 - 0.3

Step 4: Combine 'x' terms.

-0.3x = 0.9

Step 5: Isolate 'x' by dividing both sides by -0.3.

x = 0.9 / -0.3

Step 6: Simplify the value of 'x'.

x = -3

So, the solution to the equation is x = -3.
