| ( | 3127 10 | − | x | ) | ÷ | x | = | 333 500 |
| 方程两边同时乘以: | x |
| ( | 3127 10 | − | x | ) | = | 333 500 | x |
3127 10 | − | x | = | 333 500 | x |
| - | x | − | 333 500 | x | = | - | 3127 10 |
| - | 833 500 | x | = | - | 3127 10 |
3127 10 | = | 833 500 | x |
833 500 | x | = | 3127 10 |
| x | = | 3127 10 | ÷ | 833 500 |
| = | 3127 10 | × | 500 833 |
| = | 3127 | × | 50 833 |
