Question

7,2X - 5,4X +0,55 = 1

Answer 1

Ответ:

Пошаговое объяснение:

7,2х - 5,4х+0,55 = 1

1,8х = 1-0,55

1,8х=0,45

х= 0,45 : 1,8

х= 0,25

Answer 2

To solve the equation 7.2X - 5.4X + 0.55 = 1, you need to isolate the variable X. Here are the steps to solve for X:

1. First, combine like terms on the left side of the equation by adding or subtracting the X terms:

7.2X - 5.4X = 1 - 0.55

2. Simplify the left side by subtracting 5.4X from 7.2X:

(7.2 - 5.4)X = 1 - 0.55

2.8X = 0.45

3. Now, to isolate X, divide both sides of the equation by 2.8:

(2.8X) / 2.8 = 0.45 / 2.8

X = 0.45 / 2.8

4. Calculate the value of X:

X ≈ 0.1607

So, the solution to the equation 7.2X - 5.4X + 0.55 = 1 is approximately X ≈ 0.1607.
