| ( | 3127 10 | − | x | ) | ÷ | x | = | 333 5 |
| 方程两边同时乘以: | x |
| ( | 3127 10 | − | x | ) | = | 333 5 | x |
3127 10 | − | x | = | 333 5 | x |
| - | x | − | 333 5 | x | = | - | 3127 10 |
| - | 338 5 | x | = | - | 3127 10 |
3127 10 | = | 338 5 | x |
338 5 | x | = | 3127 10 |
| x | = | 3127 10 | ÷ | 338 5 |
| = | 3127 10 | × | 5 338 |
| = | 3127 2 | × | 1 338 |
| x | = | 3127 676 |
