| 3600 | = | ( | 10 | ( | 1 | − | 10 100 | ) | − | 6 | ) | x | − | 26400 |
| 方程右边 = | 10 | ( | 1 | − | 10 100 | ) | x | − | 6 | x | − | 26400 |
| = | 10 | × | 1 | x | − | 10 | × | 10 100 | x | − | 6 | x | − | 26400 |
| = | 10 | x | − | 1 | x | − | 6 | x | − | 26400 |
| = | 3 | x | − | 26400 |
| 3600 | = | 3 | x | − | 26400 |
| - | 3 | x | = | - | 26400 | − | 3600 |
| - | 3 | x | = | - | 30000 |
| 30000 | = | 3 | x |
| 3 | x | = | 30000 |
| x | = | 30000 | ÷ | 3 |
| = | 30000 | × | 1 3 |
| = | 10000 | × | 1 |
| x | = | 10000 |
