| X | − | ( | X | − | 5000 | ) | × | 3 100 | − | 12082 25 | = | 6000 |
| 方程左边 = | X | − | X | × | 3 100 | + | 5000 | × | 3 100 | − | 12082 25 |
| = | X | − | X | × | 3 100 | + | 150 | − | 12082 25 |
| = | 97 100 | X | − | 8332 25 |
97 100 | X | − | 8332 25 | = | 6000 |
97 100 | X | = | 6000 | + | 8332 25 |
97 100 | X | = | 158332 25 |
| X | = | 158332 25 | ÷ | 97 100 |
| = | 158332 25 | × | 100 97 |
| = | 158332 | × | 4 97 |
| X | = | 633328 97 |
