4∣5−2x∣<4 (subtracting 3 from both side)
∣5−2x∣<1(dividing both side by 4)
there are two case to consider now 
1st case if 
5−2x>0(basically means its positive )
so
we can take it out from the mod as it is
5-2x<1
-2x<-4
x>2(dividing both side by two and multiplying both by -1)........
multiplying with -1 changes inequality
x>2........1
now if 
5−2x<0
then we have to take it out from the mod followed by negative sign
-(
5−2x)<1
2x-5<1
2x<6(adding 5 both side)
x<3...........2
Combining 1 and 2 we get
3>x>2

1 3 1
absolute value is also the same!
