| 3 | ÷ | 2 | − | 1 | ÷ | 3 | × | x | − | 1 | = | 5 | ÷ | 6 | × | x | − | 2 |
| 方程左边 = | 3 2 | − | 1 3 | x | − | 1 |
| = | 1 2 | − | 1 3 | x |
1 2 | − | 1 3 | x | = | 5 | ÷ | 6 | × | x | − | 2 |
| 方程右边 = | 5 6 | x | − | 2 |
1 2 | − | 1 3 | x | = | 5 6 | x | − | 2 |
| - | 1 3 | x | − | 5 6 | x | = | - | 2 | − | 1 2 |
| - | 7 6 | x | = | - | 2 | − | 1 2 |
| - | 7 6 | x | = | - | 5 2 |
5 2 | = | 7 6 | x |
7 6 | x | = | 5 2 |
| x | = | 5 2 | ÷ | 7 6 |
| = | 5 2 | × | 6 7 |
| = | 5 | × | 3 7 |
| x | = | 15 7 |
| x | = | 2.142857 |
