| ( | ( | x | + | 4 | ) | ÷ | 3 | ) | − | ( | ( | 3 | x | − | 1 | ) | ÷ | 2 | ) | = | 1 |
| 方程左边 = | ( | x | + | 4 | ) | ÷ | 3 | − | ( | ( | 3 | x | − | 1 | ) | ÷ | 2 | ) |
| = | x | × | 1 3 | + | 4 | × | 1 3 | − | ( | ( | 3 | x | − | 1 | ) | ÷ | 2 | ) |
| = | x | × | 1 3 | + | 4 3 | − | ( | ( | 3 | x | − | 1 | ) | ÷ | 2 | ) |
| = | 1 3 | x | + | 4 3 | − | ( | 3 | x | − | 1 | ) | ÷ | 2 |
| = | 1 3 | x | + | 4 3 | − | 3 | x | × | 1 2 | + | 1 | × | 1 2 |
| = | 1 3 | x | + | 4 3 | − | 3 2 | x | + | 1 2 |
| = | - | 7 6 | x | + | 11 6 |
| - | 7 6 | x | + | 11 6 | = | 1 |
| - | 7 6 | x | = | 1 | − | 11 6 |
| - | 7 6 | x | = | - | 5 6 |
5 6 | = | 7 6 | x |
7 6 | x | = | 5 6 |
| x | = | 5 6 | ÷ | 7 6 |
| = | 5 6 | × | 6 7 |
| = | 5 | × | 1 7 |
| x | = | 5 7 |
