对于方程组(1),未知数个数r=方程个数s.若bi(i=1,2,3)不为零,方程有唯一解;若bi=0,则X1,X2,X3=0.

X1=d1/d.X2=d2/d,X3=d3/d.

...b1,a12,a13.....a11,b1,a13.....a11,a12,b1
d1=b1,a22,a23..d2=a21,b2,a23..d3=a21,a22,b2
...b3,a32,a33.....a31,b3,a33.....a31,a32,b3

X1=(b1a22a33+b3a12a23+b2a13a32)/362
-(b3a13a22+b2a12a33+b1a32a23)/362
=(30b1+63b3+2b2)/362-(10b3+54b2+7b1)/362
=(23b1-52b2+53b3)/362

X2=(b2a11a33+b1a23a31+b3a13a21)/362
-(b2a13a31+b1a21a33+b3a11a23)/362
=(24b2+56b1+6b3)/362-(16b2+18b1+28b3)/362
=(38b1+8b2-22b3)/362

X3=(b3a11a22+b2a12a31+b1a21a32)/362
-(b1a22a31+b3a21a12+b2a32a11)/362
=(20b3+72b2+3b1)/362-(40b1+27b3+4b2)/362
=(-37b1+68b2-7b3)/362
