11 5000 | x | ÷ | ( | 16237 50 | − | x | ) | = | 1 500 |
| 方程两边同时乘以: | ( | 16237 50 | − | x | ) |
11 5000 | x | = | 1 500 | ( | 16237 50 | − | x | ) |
11 5000 | x | = | 1 500 | × | 16237 50 | − | 1 500 | x |
11 5000 | x | = | 16237 25000 | − | 1 500 | x |
11 5000 | x | + | 1 500 | x | = | 16237 25000 |
21 5000 | x | = | 16237 25000 |
| x | = | 16237 25000 | ÷ | 21 5000 |
| = | 16237 25000 | × | 5000 21 |
| = | 16237 5 | × | 1 21 |
| x | = | 16237 105 |
| x | = | 154.638095 |
