这总共需要计算10个4阶行列式，太费篇幅。建议楼主用软件计算（譬如用excel）。
1) D=|(1,1,5,2)(2,3,11,5)(2,1,3,2)(1,1,3,4)|=-14
D1=|(1,1,5,4)(2,3,11,5)(-3,1,3,2)(-3,1,3,4)|=28
D2=|(1,1,5,2)(2,2,11,5)(2,-3,3,2)(1,-3,3,4)|=0
D3=|(1,1,1,4)(2,3,2,5)(2,1,-3,2)(1,1,-3,4)|=-14
D4=|(1,1,5,1)(2,3,11,2)(2,1,3,-3)(1,1,3,-3)|=14
∴ x1=D1/D=-2、x2=0、x3=1、x4=-1
2)仿上，可得 D=-153、D1=153、D2=153、D3=0、D4=-153
∴ x1=-1、x2=-1、x3=0、x4=1
