Given : 3x - 7 > 2(x-6),\ 6-x > 11 - 2x

 

3x - 7 > 2(x-6)\, \, \, \, and\, \, \, \, \, \ 6-x > 11 - 2x

\Rightarrow \, \, 3x - 7 > 2x-12\, \, \, \, and\, \, \, \, \, \ 6-x > 11 - 2x

\Rightarrow \, \, 3x - 2x >7-12\, \, \, \, and\, \, \, \, \, \ 2x-x > 11 - 6

\Rightarrow \, \, x >-5\, \, \, \, and\, \, \, \, \, \ x > 5

       x\in (5,\infty )

The solution graphically on the number line is as shown :
