详细信息: 输入的方程组为:
 | | | | | 5313 25 | A | + | | | 2944 25 | B | + | | | 7083 50 | C | + | | | 20983 50 | D | + | | | 3533 50 | E | + | | | 5233 50 | F | + | | | 12383 50 | G | + | | | 14183 50 | H | + | | | 6833 50 | I | + | | | 3883 50 | J | + | | | 3233 50 | K | + | | | 6833 50 | L | + | | | 5233 50 | M | = | | 34527 | | (1) |
| | | | | | | | | | | | | 解题过程:
将未知数的系数化为1,方程组化为:
 | | | | A | + | | | 128 231 | B | + | | | 2361 3542 | C | + | | | 20983 10626 | D | + | | | 3533 10626 | E | + | | | 5233 10626 | F | + | | | 1769 1518 | G | + | | | 14183 10626 | H | + | | | 6833 10626 | I | + | | | 353 966 | J | + | | | 3233 10626 | K | + | | | 6833 10626 | L | + | | | 5233 10626 | M | = | | | 287725 1771 | | (1) |
| | | | | | | | | | | | |
所以,方程组的解为:
 | | | A = | | | 287725 1771 | - | | | 128 231 | B | - | | | 2361 3542 | C | - | | | 20983 10626 | D | - | | | 3533 10626 | E | - | | | 5233 10626 | F | - | | | 1769 1518 | G | - | | | 14183 10626 | H | - | | | 6833 10626 | I | - | | | 353 966 | J | - | | | 3233 10626 | K | - | | | 6833 10626 | L | - | | | 5233 10626 | M |
|
将方程组的解化为小数:
 | | | A = | | 162.464709 | - | | | 128 231 | B | - | | | 2361 3542 | C | - | | | 20983 10626 | D | - | | | 3533 10626 | E | - | | | 5233 10626 | F | - | | | 1769 1518 | G | - | | | 14183 10626 | H | - | | | 6833 10626 | I | - | | | 353 966 | J | - | | | 3233 10626 | K | - | | | 6833 10626 | L | - | | | 5233 10626 | M |
|
其中: B, C, D, E, F, G, H, I, J, K, L, M 为任意常数。 解方程组的详细方法请参阅:《多元一次方程组的解法》 |
