A=matrix(QQ,3,3,[2,0,4,2,10,6,4,8,0]) I=identity_matrix(3) A.augment(I).echelon_form() 
       
[    1     0     0   1/4  -1/6  5/24]
[    0     1     0  -1/8  1/12  1/48]
[    0     0     1   1/8  1/12 -5/48]
[    1     0     0   1/4  -1/6  5/24]
[    0     1     0  -1/8  1/12  1/48]
[    0     0     1   1/8  1/12 -5/48]
