| 方程左边 = | - | 3 4 | x | − | 2 |
| - | 3 4 | x | − | 2 | = | - | 9 | ÷ | 23 | × | x | + | 51 | ÷ | 23 |
| 方程右边 = | - | 9 23 | x | + | 51 23 |
| - | 3 4 | x | − | 2 | = | - | 9 23 | x | + | 51 23 |
| - | 3 4 | x | + | 9 23 | x | = | 51 23 | + | 2 |
| - | 33 92 | x | = | 51 23 | + | 2 |
| - | 33 92 | x | = | 97 23 |
| - | 97 23 | = | 33 92 | x |
33 92 | x | = | - | 97 23 |
| x | = | - | 97 23 | ÷ | 33 92 |
| = | - | 97 23 | × | 92 33 |
| = | - | 97 | × | 4 33 |
