3次线性方程组求解3个未知数计算工具

例如，解3次方程和3个未知数：文章源自公式库网-https://www.gongshiku.com/html/201912/3cixianxingfangchengzuqiujie3geweizhishujisuangongju.html

x + 2y + 3z = 9
2x -  y +  z = 8
3x      -  z = 3

这将是输入上文的矩阵：文章源自公式库网-https://www.gongshiku.com/html/201912/3cixianxingfangchengzuqiujie3geweizhishujisuangongju.html

1   2   3  : 9
2  -1   1  : 8
3   0  -1  : 3

结果：文章源自公式库网-https://www.gongshiku.com/html/201912/3cixianxingfangchengzuqiujie3geweizhishujisuangongju.html

x =  2
y = -1
z =  3
