Solution:  The given system of equations is 

            \ 3x+2y=13 ............(1)\ \ 6x-4y=10 ............(2)

Form (1) ,we get 

           \Rightarrow 2y=13-3x

Substituting  \ 2y=13-3x  in (2) we get  

\ Rightarrow 6x-2(13-3x)=10 \ \ Rightarrow 6x-26+6x=10\ \ Rightarrow 12x=36Rightarrow x=3

Putting  \ x=3 in  \ 2y=13-3x\ \ Rightarrow 2y=4Rightarrow y=2

Hence , the solution of the given system of equation is \ x=3 , \ y=2
