| ( | - | 2311 50 | − | x | ) | ÷ | x | = | 53 250 |
| 方程两边同时乘以: | x |
| ( | - | 2311 50 | − | x | ) | = | 53 250 | x |
| - | 2311 50 | − | x | = | 53 250 | x |
| - | x | − | 53 250 | x | = | 2311 50 |
| - | 303 250 | x | = | 2311 50 |
| - | 2311 50 | = | 303 250 | x |
303 250 | x | = | - | 2311 50 |
| x | = | - | 2311 50 | ÷ | 303 250 |
| = | - | 2311 50 | × | 250 303 |
| = | - | 2311 | × | 5 303 |
