| 2 | x | ÷ | ( | 2212 | − | x | ) | = | 11 10 |
| 方程两边同时乘以: | ( | 2212 | − | x | ) |
| 2 | x | = | 11 10 | ( | 2212 | − | x | ) |
| 2 | x | = | 11 10 | × | 2212 | − | 11 10 | x |
| 2 | x | = | 12166 5 | − | 11 10 | x |
| 2 | x | + | 11 10 | x | = | 12166 5 |
31 10 | x | = | 12166 5 |
| x | = | 12166 5 | ÷ | 31 10 |
| = | 12166 5 | × | 10 31 |
| = | 12166 | × | 2 31 |
| x | = | 24332 31 |
| x | = | 784.903226 |
