Answer 2

To solve the equations:

1. |x| = -9
2. |-x| = |3,6|

Let's break them down one by one:

1. |x| = -9

The absolute value of any real number is always non-negative, so it can never be equal to a negative number like -9. Therefore, there are no solutions to this equation.

2. |-x| = |3,6|

The absolute value of a number is always non-negative, so |-x| is non-negative. Likewise, |3,6| is non-negative. So, we have:

|-x| ≥ 0 |3,6| ≥ 0

Now, to find the solution to this equation, we need to consider two cases:

Case 1: |-x| = |3,6| = 0

If |-x| = |3,6| = 0, then x must be 0 because the absolute value of any real number is 0 only when the number itself is 0.

Case 2: |-x| ≠ |3,6| (any non-zero value)

If |-x| ≠ |3,6|, then there are no solutions in this case because we can't find a real number x that satisfies this condition. The absolute value of a number is never negative, so it can't be equal to a non-zero value like |3,6|.

In summary, there is only one solution to the second equation, which is:

x = 0
