| x | = | 307 2500 | ( | 168 | − | x | ) |
| 方程右边 = | 307 2500 | × | 168 | − | 307 2500 | x |
| = | 12894 625 | − | 307 2500 | x |
| x | = | 12894 625 | − | 307 2500 | x |
| x | + | 307 2500 | x | = | 12894 625 |
2807 2500 | x | = | 12894 625 |
| x | = | 12894 625 | ÷ | 2807 2500 |
| = | 12894 625 | × | 2500 2807 |
| = | 1842 | × | 4 401 |
| x | = | 7368 401 |
