| X | ÷ | ( | 396057 100 | + | X | ) | = | 6 625 |
| 方程两边同时乘以: | ( | 396057 100 | + | X | ) |
| X | = | 6 625 | ( | 396057 100 | + | X | ) |
| X | = | 6 625 | × | 396057 100 | + | 6 625 | X |
| X | = | 1188171 31250 | + | 6 625 | X |
| X | − | 6 625 | X | = | 1188171 31250 |
619 625 | X | = | 1188171 31250 |
| X | = | 1188171 31250 | ÷ | 619 625 |
| = | 1188171 31250 | × | 625 619 |
