| 1600 | × | 3 | ÷ | x | = | 6000 | ÷ | ( | x | + | 2 | ) |
| 方程两边同时乘以: | x | , | ( | x | + | 2 | ) |
| 1600 | × | 3 | ( | x | + | 2 | ) | = | 6000 | x |
| 1600 | × | 3 | x | + | 1600 | × | 3 | × | 2 | = | 6000 | x |
| 4800 | x | + | 9600 | = | 6000 | x |
| 4800 | x | − | 6000 | x | = | - | 9600 |
| - | 1200 | x | = | - | 9600 |
| 9600 | = | 1200 | x |
| 1200 | x | = | 9600 |
| x | = | 9600 | ÷ | 1200 |
| = | 9600 | × | 1 1200 |
| = | 8 | × | 1 |
