Given : 2(x-1)<x+5,\ 3(x+2)> 2 -x

 

2(x-1)<x+5\, \, \, \, and\, \, \, \, \, \ 3(x+2)> 2 -x

\Rightarrow \, \, 2x-2<x+5\, \, \, \, and\, \, \, \, \, \ 3x+6> 2 -x

\Rightarrow \, \, 2x-x<2+5\, \, \, \, and\, \, \, \, \, \ 3x+x> 2 -6

\Rightarrow \, \, x<7\, \, \, \, and\, \, \, \, \, \ 4x> -4

\Rightarrow \, \, x<7\, \, \, \, and\, \, \, \, \, \ x> -1

       (-1,7)

The solution graphically on the number line is as shown :
