1) |2х - 5| = 3 2) |х + 6| = 1 3) |4х - 2| = 6 4) |х| + х = 2 5) |х| - х = 1

Question

1) |2х - 5| = 3
2) |х + 6| = 1
3) |4х - 2| = 6
4) |х| + х = 2
5) |х| - х = 1

Answer 1

|2х-5|=3
2х-5=3
2х=5-3
2х=2
х=1
|х+6|=1
х+6=1
х=6+1
х=7
|4х-2|=6
4х-2=6
4х=-2+6
4х=8
х=2
|х|+х=2
х+х=2
2х=2
х=1
|х|-х=1
х-х=1
0х=1
х=0
