详细信息: 输入的方程组为:
 | | | | 2 | A | + | | 16 | B | + | | 10 | C | + | | 6 | D | + | | 10 | E | + | | F | + | | 9 | G | + | | 12 | H | + | | 20 | I | = | | 42702 | | (1) |
| | | | | | | | | | | | | | | | | | | 解题过程:
将未知数的系数化为1,方程组化为:
 | | | | A | + | | 8 | B | + | | 5 | C | + | | 3 | D | + | | 5 | E | + | | | 1 2 | F | + | | | 9 2 | G | + | | 6 | H | + | | 10 | I | = | | 21351 | | (1) |
| | | | | | | | | | | | | | | | | | |
所以,方程组的解为:
 | | | A = | | 21351 | - | | 8 | B | - | | 5 | C | - | | 3 | D | - | | 5 | E | - | | | 1 2 | F | - | | | 9 2 | G | - | | 6 | H | - | | 10 | I |
|
其中: B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S 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》 |
