| 2 | x | − | 3 | ÷ | 4 | − | x | + | 5 | ÷ | 2 | = | 2 | x | + | 1 | ÷ | 3 | − | 4 |
| 方程左边 = | 2 | x | − | 3 4 | − | x | + | 5 2 |
| = | 1 | x | + | 7 4 |
| 1 | x | + | 7 4 | = | 2 | x | + | 1 | ÷ | 3 | − | 4 |
| 方程右边 = | 2 | x | + | 1 3 | − | 4 |
| = | 2 | x | − | 11 3 |
| 1 | x | + | 7 4 | = | 2 | x | − | 11 3 |
| 1 | x | − | 2 | x | = | - | 11 3 | − | 7 4 |
| - | x | = | - | 11 3 | − | 7 4 |
| - | x | = | - | 11 3 | − | 7 4 |
| - | x | = | - | 65 12 |
65 12 | = | x |
| x | = | 65 12 |
