A.X=B
X= A Invers . B

A Invers = 1/ determinan A x adjoin A
A Invers = 1/-6-2 . [-2     -1]
                                  [ -2      3]
A Invers = 1/-8 . [-2     -1]
                               [ -2      3]
A Invers = [1/4        1/8]
                    [1/4      -3/8]

X = A Invers x B
X= [1/4        1/8] [17     21]
      [1/4      -3/8] [-2     -18]
X= [4,25-0,25       5,25-2,25] 
      [4,25+0,75      5,25+6,75]
X= [4      3] 
      [5    12].        A.
