嫌な予感しかしないからwolframにぶち込んでみた
Inverse{{3,1,2,5,2,2},{5,2,3,3,1,2},{2,0,1,5,3,4},{4,3,5,2,1,2},{1,2,3,5,6,4},{6,4,1,4,3,3}}
={{-41/165, 28/33, -23/165, -73/165, 2/15, -16/165},
{197/660, -145/132, 13/330, 391/660, -7/30, 131/330},
{-1/220, 9/44, -9/110, 17/220, 1/10, -23/110},
{71/132, -71/132, 1/66, 25/132, -1/6, 5/66},
{-46/165, 29/33, -58/165, -98/165, 7/15, -26/165},
{-223/660, -61/132, 193/330, 271/660, -7/30, 41/330}}
手計算は可能とはいえあまりやりたくねえな
