| 3 | ÷ | 5 | − | 10 | x | ÷ | 3 | = | 6 | ÷ | 5 | + | 10 | x |
| 方程左边 = | 3 5 | − | 10 3 | x |
3 5 | − | 10 3 | x | = | 6 | ÷ | 5 | + | 10 | x |
| 方程右边 = | 6 5 | + | 10 | x |
3 5 | − | 10 3 | x | = | 6 5 | + | 10 | x |
| - | 10 3 | x | − | 10 | x | = | 6 5 | − | 3 5 |
| - | 40 3 | x | = | 6 5 | − | 3 5 |
| - | 40 3 | x | = | 3 5 |
| - | 3 5 | = | 40 3 | x |
40 3 | x | = | - | 3 5 |
| x | = | - | 3 5 | ÷ | 40 3 |
| = | - | 3 5 | × | 3 40 |
| x | = | - | 9 200 |
| x | = | - 0.045 |
