    Represent the solutions sets of the following equation on a number line...\[\left| x+3 \right| > 1\] and \[\left| 2x + 5 \right| < 3\]

    |a| = -a if a<0 |a| = a if a>0 so solve (x+3)>1 & -(x+3)>1 (2x+5)<3 & -(2x+5)<3

    now 'AND' means the common region between them what is common from x>-2 , x<-4 and x<-1 , x>-4 ?
