| 9250 | = | 340 | ÷ | ( | 10 100 | − | x | ) |
| 方程两边同时乘以: | ( | 10 100 | − | x | ) |
| 9250 | ( | 10 100 | − | x | ) | = | 340 |
| 9250 | × | 10 100 | − | 9250 | x | = | 340 |
| 925 | − | 9250 | x | = | 340 |
| - | 9250 | x | = | 340 | − | 925 |
| - | 9250 | x | = | - | 585 |
| 585 | = | 9250 | x |
| 9250 | x | = | 585 |
| x | = | 585 | ÷ | 9250 |
| = | 585 | × | 1 9250 |
| = | 117 | × | 1 1850 |
| x | = | 117 1850 |
| x | = | 0.063243 |
