线性代数,矩阵,求详解,一定要有详解…

增广矩阵=
1 3 -2 1 1 1
1 3 -2 3 2 3
1 3 -2 3 4 4
r3-r2,r2-r1
1 3 -2 1 1 1
0 0 0 2 1 2
0 0 0 0 2 1
r3*(1/2),r1-r3,r2-r3
1 3 -2 1 0 1/2
0 0 0 2 0 3/2
0 0 0 0 1 1/2
r2*(1/2),r1-r2
1 3 -2 0 0 -1/4
0 0 0 1 0 3/4
0 0 0 0 1 1/2
方程组的通解为 (-1/4,0,0,3/4,1/2)^T + k1(-3,1,0,0,0)^T + k2(2,0,1,0,0)^T
