Question

Salut, vreau si eu 5 inecuatii cu modul, 5 ecuatii cu modul rezolvate, repede.
DAU COROANA
CAT MAI SIMPLE SI SCURTE

Answer 1

Inecuatii:

|x+1|<3
x<3-1
x>-3-1
-4<x<2

|x/2|>=10
x>=10*2
x<=-10*2

|x*2|<8
x<8/2
x>-8/2
-4<x<4

|x-4|>11
x>11+4
x<-11+4

|x| > 13
x > 13
x < -13

ecuatii


|x+1|=2
x+1=2 x+1=-2
x=1 x=-3

|x*2|=10
x*2=10 x*2=-10
x=5 x=-5

|x/3|=3
x/3=3 x/3=-3
x= 9 x=-9

|x-8|=4
x-8=4 x-8=-4
x=12 x=4

|x*4|=0
x=0
