详细信息: 输入的方程组为:
| | | | 5 | A | + | | 5 | B | + | | 9 | C | + | | 9 | D | + | | 6 | E | + | | 6 | F | + | | 8 | G | + | | 9 | H | + | | 8 | I | + | | 5 | J | + | | 5 | K | + | | 6 | L | + | | 9 | M | + | | 6 | N | = | | 0 | | (1) |
| | | | | | | | | | | | | | 解题过程:
将未知数的系数化为1,方程组化为:
| | | | A | + | | B | + | | | 9 5 | C | + | | | 9 5 | D | + | | | 6 5 | E | + | | | 6 5 | F | + | | | 8 5 | G | + | | | 9 5 | H | + | | | 8 5 | I | + | | J | + | | K | + | | | 6 5 | L | + | | | 9 5 | M | + | | | 6 5 | N | = | | 0 | | (1) |
| | | | | | | | | | | | | |
所以,方程组的解为:
| | | A = | - | 1 | B | - | | | 9 5 | C | - | | | 9 5 | D | - | | | 6 5 | E | - | | | 6 5 | F | - | | | 8 5 | G | - | | | 9 5 | H | - | | | 8 5 | I | - | | 1 | J | - | | 1 | K | - | | | 6 5 | L | - | | | 9 5 | M | - | | | 6 5 | N |
|
其中: B, C, D, E, F, G, H, I, J, K, L, M, N 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》 |
