| X | ÷ | 126 | − | 50 | ÷ | 500 | − | 25 | ÷ | 1000 | − | 25 | ÷ | 1650 | = | 1 1000 | ( | 100 | + | X | ) |
| 方程左边 = | X | × | 1 126 | − | 1 10 | − | 1 40 | − | 1 66 |
| = | 1 126 | X | − | 37 264 |
1 126 | X | − | 37 264 | = | 1 1000 | ( | 100 | + | X | ) |
| 方程右边 = | 1 1000 | × | 100 | + | 1 1000 | X |
| = | 1 10 | + | 1 1000 | X |
1 126 | X | − | 37 264 | = | 1 10 | + | 1 1000 | X |
1 126 | X | − | 1 1000 | X | = | 1 10 | + | 37 264 |
437 63000 | X | = | 1 10 | + | 37 264 |
437 63000 | X | = | 317 1320 |
| X | = | 317 1320 | ÷ | 437 63000 |
| = | 317 1320 | × | 63000 437 |
| = | 317 11 | × | 525 437 |
