| 1600 | ÷ | x | = | 18000 | ÷ | ( | x | + | 2 | ) |
| 方程两边同时乘以: | x | , | ( | x | + | 2 | ) |
| 1600 | ( | x | + | 2 | ) | = | 18000 | x |
| 1600 | x | + | 1600 | × | 2 | = | 18000 | x |
| 1600 | x | + | 3200 | = | 18000 | x |
| 1600 | x | − | 18000 | x | = | - | 3200 |
| - | 16400 | x | = | - | 3200 |
| 3200 | = | 16400 | x |
| 16400 | x | = | 3200 |
| x | = | 3200 | ÷ | 16400 |
| = | 3200 | × | 1 16400 |
| = | 8 | × | 1 41 |
| x | = | 8 41 |
