| ( | X | − | 1023 | − | 5000 | ) | × | 3 10 | = | X | − | 484653 50 | − | 1023 |
| 方程左边 = | X | × | 3 10 | − | 1023 | × | 3 10 | − | 5000 | × | 3 10 |
| = | X | × | 3 10 | − | 3069 10 | − | 1500 |
| = | 3 10 | X | − | 18069 10 |
3 10 | X | − | 18069 10 | = | X | − | 484653 50 | − | 1023 |
| 方程右边 = | X | − | 535803 50 |
3 10 | X | − | 18069 10 | = | X | − | 535803 50 |
3 10 | X | − | X | = | - | 535803 50 | + | 18069 10 |
| - | 7 10 | X | = | - | 535803 50 | + | 18069 10 |
| - | 7 10 | X | = | - | 222729 25 |
222729 25 | = | 7 10 | X |
7 10 | X | = | 222729 25 |
| X | = | 222729 25 | ÷ | 7 10 |
| = | 222729 25 | × | 10 7 |
| = | 222729 5 | × | 2 7 |
