| ( | 2 | x | − | 1 | ) | ÷ | 5 | − | ( | x | − | 2 | ) | ÷ | 3 | = | 1 | ÷ | 4 |
| 方程左边 = | 2 | x | × | 1 5 | − | 1 | × | 1 5 | − | ( | x | − | 2 | ) | × | 1 3 |
| = | 2 5 | x | − | 1 5 | − | ( | x | − | 2 | ) | × | 1 3 |
| = | 2 5 | x | − | 1 5 | − | x | × | 1 3 | + | 2 | × | 1 3 |
| = | 2 5 | x | − | 1 5 | − | x | × | 1 3 | + | 2 3 |
| = | 1 15 | x | + | 7 15 |
1 15 | x | + | 7 15 | = | 1 | ÷ | 4 |
| 方程右边 = | 1 4 |
1 15 | x | + | 7 15 | = | 1 4 |
1 15 | x | = | 1 4 | − | 7 15 |
1 15 | x | = | - | 13 60 |
| x | = | - | 13 60 | ÷ | 1 15 |
| = | - | 13 60 | × | 15 |
| = | - | 13 4 | × | 1 |
| x | = | - | 13 4 |
| x | = | - 3.25 |
