| ( | x | + | 1 | ) | ÷ | 2 | − | ( | 2 | x | + | 1 | ) | ÷ | 3 | = | 1 | ÷ | 6 |
| 方程左边 = | x | × | 1 2 | + | 1 | × | 1 2 | − | ( | 2 | x | + | 1 | ) | × | 1 3 |
| = | x | × | 1 2 | + | 1 2 | − | ( | 2 | x | + | 1 | ) | × | 1 3 |
| = | 1 2 | x | + | 1 2 | − | 2 | x | × | 1 3 | − | 1 | × | 1 3 |
| = | 1 2 | x | + | 1 2 | − | 2 3 | x | − | 1 3 |
| = | - | 1 6 | x | + | 1 6 |
| - | 1 6 | x | + | 1 6 | = | 1 | ÷ | 6 |
| 方程右边 = | 1 6 |
| - | 1 6 | x | + | 1 6 | = | 1 6 |
| - | 1 6 | x | = | 1 6 | − | 1 6 |
| - | 1 6 | x | = | 0 |
| - | 0 | = | 1 6 | x |
1 6 | x | = | - | 0 |
| x | = | - | 0 | ÷ | 1 6 |
| = | - | 0 | × | 6 |
| = | - | 0 | × | 1 |
| x | = | 0 |
