| 1 | − | 2 | ÷ | 3 | × | x | = | 3 | x | + | 5 | ÷ | 2 |
| 方程左边 = | 1 | − | 2 3 | x |
| 1 | − | 2 3 | x | = | 3 | x | + | 5 | ÷ | 2 |
| 方程右边 = | 3 | x | + | 5 2 |
| 1 | − | 2 3 | x | = | 3 | x | + | 5 2 |
| - | 2 3 | x | − | 3 | x | = | 5 2 | − | 1 |
| - | 11 3 | x | = | 5 2 | − | 1 |
| - | 11 3 | x | = | 3 2 |
| - | 3 2 | = | 11 3 | x |
11 3 | x | = | - | 3 2 |
| x | = | - | 3 2 | ÷ | 11 3 |
| = | - | 3 2 | × | 3 11 |
| x | = | - | 9 22 |
| x | = | - 0.409091 |
