x-x-2>=0 inequation
The solution
Detail solution
Given the inequality:
$$\left(- x + x\right) - 2 \geq 0$$
To solve this inequality, we must first solve the corresponding equation:
$$\left(- x + x\right) - 2 = 0$$
Solve:
This equation has no roots,
this inequality is executed for any x value or has no solutions
check it
subtitute random point x, for example
$$-2 - 0 \geq 0$$
but
so the inequality has no solutions
$$\left(- x + x\right) - 2 \geq 0$$

subtitute random point x, for example
x0 = 0
$$-2 - 0 \geq 0$$
-2 >= 0
but
-2 < 0
so the inequality has no solutions
