Question

5,2х-3,2(-4,04)-(х+3,5)=23,2

Answer 1

Ответ:

-2,22

Пошаговое объяснение:

-5,2x+12,9-x-3,5=23,2

-6,2x=23,2+3,5-12,9

-6,2x=13,8

x= - 13,8/6,2

x= - 2,22.

Answer 2

To solve the given equation, let's simplify the expression and then isolate the variable x.

Given equation: 5(2x) - 3(2)(-4.04) - (x + 3.5) = 23.2

First, simplify the expression within the brackets:

5(2x) - 3(2)(-4.04) - x - 3.5 = 23.2

10x + 24.24 - x - 3.5 = 23.2

Combine like terms:

9x + 20.74 = 23.2

Next, isolate the variable x by moving the constant term to the other side of the equation:

9x = 23.2 - 20.74

9x = 2.46

Now, divide both sides of the equation by 9 to solve for x:

x = 2.46 / 9

x ≈ 0.273

Therefore, the solution to the equation is x ≈ 0.273.
