| ( | 1 | − | 2 | x | ) | ÷ | 3 | − | ( | x | + | 1 | ) | ÷ | 6 | = | 2 |
| 方程左边 = | 1 | × | 1 3 | − | 2 | x | × | 1 3 | − | ( | x | + | 1 | ) | × | 1 6 |
| = | 1 3 | − | 2 3 | x | − | ( | x | + | 1 | ) | × | 1 6 |
| = | 1 3 | − | 2 3 | x | − | x | × | 1 6 | − | 1 | × | 1 6 |
| = | 1 3 | − | 2 3 | x | − | x | × | 1 6 | − | 1 6 |
| = | 1 6 | − | 5 6 | x |
1 6 | − | 5 6 | x | = | 2 |
| - | 5 6 | x | = | 2 | − | 1 6 |
| - | 5 6 | x | = | 11 6 |
| - | 11 6 | = | 5 6 | x |
5 6 | x | = | - | 11 6 |
| x | = | - | 11 6 | ÷ | 5 6 |
| = | - | 11 6 | × | 6 5 |
| = | - | 11 | × | 1 5 |
| x | = | - | 11 5 |
| x | = | - 2.2 |
