| x | ÷ | 59 250 | = | ( | x | − | 18 | ) | ÷ | 9 250 |
| 方程右边 = | x | × | 250 9 | − | 18 | × | 250 9 |
| = | x | × | 250 9 | − | 500 |
250 59 | x | = | 250 9 | x | − | 500 |
250 59 | x | − | 250 9 | x | = | - | 500 |
| - | 12500 531 | x | = | - | 500 |
| 500 | = | 12500 531 | x |
12500 531 | x | = | 500 |
| x | = | 500 | ÷ | 12500 531 |
| = | 500 | × | 531 12500 |
| = | 1 | × | 531 25 |
| x | = | 531 25 |
| x | = | 21.24 |
