| 1 | ÷ | 2 | × | x | − | 1 | ÷ | 3 | = | - | x | ÷ | 3 | + | 1 | + | 4 | ÷ | 3 | × | x |
| 方程左边 = | 1 2 | x | − | 1 3 |
1 2 | x | − | 1 3 | = | - | x | ÷ | 3 | + | 1 | + | 4 | ÷ | 3 | × | x |
| 方程右边 = | - | x | × | 1 3 | + | 1 | + | 4 3 | x |
| = | 1 | x | + | 1 |
1 2 | x | − | 1 3 | = | 1 | x | + | 1 |
1 2 | x | − | 1 | x | = | 1 | + | 1 3 |
| - | 1 2 | x | = | 1 | + | 1 3 |
| - | 1 2 | x | = | 4 3 |
| - | 4 3 | = | 1 2 | x |
1 2 | x | = | - | 4 3 |
| x | = | - | 4 3 | ÷ | 1 2 |
| = | - | 4 3 | × | 2 |
| x | = | - | 8 3 |
| x | = | - 2.666667 |
