| ( | x | − | 8191 | ) | ÷ | x | × | 100 100 | = | 9 200 |
| 方程两边同时乘以: | x |
| ( | x | − | 8191 | ) | × | 100 100 | = | 9 200 | x |
| x | × | 100 100 | − | 8191 | × | 100 100 | = | 9 200 | x |
| x | × | 100 100 | − | 8191 | = | 9 200 | x |
100 100 | x | − | 9 200 | x | = | 8191 |
191 200 | x | = | 8191 |
| x | = | 8191 | ÷ | 191 200 |
| = | 8191 | × | 200 191 |
| x | = | 1638200 191 |
| x | = | 8576.963351 |
