115 | X | + | 29 | × | 581 5 | = | ( | X | + | 29 | ) | × | 116 |
方程左边 = | 115 | X | + | 16849 5 |
115 | X | + | 16849 5 | = | ( | X | + | 29 | ) | × | 116 |
方程右边 = | X | × | 116 | + | 29 | × | 116 |
= | X | × | 116 | + | 3364 |
115 | X | + | 16849 5 | = | 116 | X | + | 3364 |
115 | X | − | 116 | X | = | 3364 | − | 16849 5 |
- | X | = | 3364 | − | 16849 5 |
- | X | = | 3364 | − | 16849 5 |
- | X | = | - | 29 5 |
29 5 | = | X |
X | = | 29 5 |
