| ( | X | − | 1023 | − | 5000 | ) | × | 3 100 | = | X | − | 373783 50 | − | 1023 |
| 方程左边 = | X | × | 3 100 | − | 1023 | × | 3 100 | − | 5000 | × | 3 100 |
| = | X | × | 3 100 | − | 3069 100 | − | 150 |
| = | 3 100 | X | − | 18069 100 |
3 100 | X | − | 18069 100 | = | X | − | 373783 50 | − | 1023 |
| 方程右边 = | X | − | 424933 50 |
3 100 | X | − | 18069 100 | = | X | − | 424933 50 |
3 100 | X | − | X | = | - | 424933 50 | + | 18069 100 |
| - | 97 100 | X | = | - | 424933 50 | + | 18069 100 |
| - | 97 100 | X | = | - | 831797 100 |
831797 100 | = | 97 100 | X |
97 100 | X | = | 831797 100 |
| X | = | 831797 100 | ÷ | 97 100 |
| = | 831797 100 | × | 100 97 |
| = | 831797 | × | 1 97 |
| X | = | 831797 97 |
| X | = | 8575.226804 |
