Verified answer
4I3х - 9I = 0;|3х-9|=0
3х-9=0
х=3
-----------
I0,5х - 1I = -5;
0.5х-1=0
х=2
----------
I2 + хI + 4 = 16;
|2+х|=16-4
|2+х|=12
2+х=12
2х=-12
х=10
х=-14
------------
-IхI=-5,4;
|x|=5.4
x=5.4
х=-5.4
------------
IIхI - 5I=1;
|5х|=1
5х=1
5х=-1
х=1/5
х=-1/5
-------------
I4х + 1I=3;
4х+1=3
4х+1=-3
х=1/2
х=-1
-------------
I1 - 2хI=0;
1-2х=0
х=1/2; 0,5
-------------
6IхI - 9 = 45.
6*|х|=45+9
6*|х|=54
|х|=9
х=9
х=-9
