2) x1=  1,8    x2= - 1,8

Пошаговое объяснение:

1)|x|=4,5

  x1= - 4,5    x2=4,5

Ответ:  x1= - 4,5    x2=4,5

2)|x|= -1,8

  x1=  1,8    x2= - 1,8

Ответ:  x1=  1,8    x2= - 1,8

Answer 2

It seems like you're providing two equations involving absolute values of "x." I'll help you solve each of them:

1. |x| = 4.5: To solve this equation, you need to consider two cases:

Case 1: x is positive or zero. In this case, |x| is equal to x. So, the equation becomes: x = 4.5

Case 2: x is negative. In this case, |x| is equal to -x. So, the equation becomes: -x = 4.5

Now, solve for x in the second case: -x = 4.5 x = -4.5

So, there are two solutions for |x| = 4.5: x = 4.5 and x = -4.5.

2. |x| = -1.8: This equation has no real solutions because the absolute value of any real number is always non-negative. Therefore, there are no values of "x" that will make the absolute value of "x" equal to a negative number.

In summary:

1. For |x| = 4.5, the solutions are x = 4.5 and x = -4.5.
2. There are no real solutions for |x| = -1.8.
