Question 2300
 
 2x + 3y = 19   ....    ......(1)
 5x - 4y = -33  ....    ......(2)
 (1)*4, we get
 8x + 12y = 76  ....    ......(3)
 (2)*3, we get
 15x - 12y = -99 ...    ......(4)
(3)+(4) we get
 23x = -23
 so x = {{{-23/23}}}  = -1
 By substituting the value of x in Eq.(1)
 -2 + 3y = 19
So 3y = 19 + 2  =  21
 So y = {{{21/3}}}  =  7

  x = -1;  & y = 7  Ans.
