i ) 217 x + 131 y = 913                             ----- ( 1 )

And

131 x + 217 y = 827                               ----- ( 2 )

Now we multiply by 217 in equation 1 and by 131 in equation 2 , We get

47089 x + 28427 y = 198121                 ----- ( 3 )

And

17161 x + 28427 y = 108337                 ----- ( 4 )

Now we subtract equation 4 from equation 3 and get

29928 x = 89784

x = 8978429928

x = 3 , Substitute that value in equation 1 , we get

217 ( 3 ) + 131 y = 913

651 + 131 y = 913

131 y = 262

y = 262131

y = 2

So,

x = 3 and y = 2

22adi52003: u could have solved it by first adding subtracting and adding method

22adi52003: instead of multiplyong and complicating the linear eqns

22adi52003: *multiplying

Anonymous: yes this is lengthy method but good attempt !
