      Three equations are,

      2x-y+2x=6
      X-2y+3z=6
      3x-3y-z=-6

      We know that

      A X = B

      2    -1    +2      x              6
      1    -2    +3      y       =    6
      3    -3    -1       z             -6


      X = A^-1  B

      Now calculate A^1 and multiply it with B.
      You will get X, i.e. X,y and z.
