| 27600 | ÷ | x | = | 33000 | ÷ | ( | 5 | ÷ | 4 | × | x | + | 10 | ) |
| 方程两边同时乘以: | x | , | ( | 5 | ÷ | 4 | × | x | + | 10 | ) |
| 27600 | ( | 5 | ÷ | 4 | × | x | + | 10 | ) | = | 33000 | x |
| 27600 | × | 5 | ÷ | 4 | × | x | + | 27600 | × | 10 | = | 33000 | x |
| 34500 | x | + | 276000 | = | 33000 | x |
| 34500 | x | − | 33000 | x | = | - | 276000 |
| 1500 | x | = | - | 276000 |
| x | = | - | 276000 | ÷ | 1500 |
| = | - | 276000 | × | 1 1500 |
| = | - | 184 | × | 1 |
