this done by another methods, [ ELIMINATION METHOD ]
   
       3x + 2y = 11                                         2x + 3y = 4
      {3x+2y =11} * 3                                  {2x+3y = 4 } * 2    (by eliminating Y)
       9x+6y=33       ----------[1]                      4x+6y=8               ----------[2]

by subtracting [1] and [2]
    
               9x + 6y = 33
          -  ( 4x + 6y = 8  )
               ___________ 
               5x  + 0   = 25     
                          5x=25
                             x= 5

putting the value of x in [1]

3x5 + 2y = 11
15  + 2y = 11
2y= -4
y=-2
