| 16 | × | 3 2 | x | ÷ | ( | x | + | 2000 | ) | = | 16 | x | ÷ | ( | x | + | 2000 | ) | + | 4 |
| 方程两边同时乘以: | ( | x | + | 2000 | ) |
| 16 | × | 3 2 | x | = | 16 | x | + | 4 | ( | x | + | 2000 | ) |
| 16 | × | 3 2 | x | = | 16 | x | + | 4 | x | + | 4 | × | 2000 |
| 24 | x | = | 16 | x | + | 4 | x | + | 8000 |
| 24 | x | = | 20 | x | + | 8000 |
| 24 | x | − | 20 | x | = | 8000 |
| 4 | x | = | 8000 |
| x | = | 8000 | ÷ | 4 |
| = | 8000 | × | 1 4 |
