| ( | x | − | 2 | ) | ÷ | 3 | − | 2 | = | ( | 4 | x | + | 2 | ) | ÷ | 9 |
| 方程左边 = | x | × | 1 3 | − | 2 | × | 1 3 | − | 2 |
| = | x | × | 1 3 | − | 2 3 | − | 2 |
| = | 1 3 | x | − | 8 3 |
1 3 | x | − | 8 3 | = | ( | 4 | x | + | 2 | ) | ÷ | 9 |
| 方程右边 = | 4 | x | × | 1 9 | + | 2 | × | 1 9 |
| = | 4 9 | x | + | 2 9 |
1 3 | x | − | 8 3 | = | 4 9 | x | + | 2 9 |
1 3 | x | − | 4 9 | x | = | 2 9 | + | 8 3 |
| - | 1 9 | x | = | 2 9 | + | 8 3 |
| - | 1 9 | x | = | 26 9 |
| - | 26 9 | = | 1 9 | x |
1 9 | x | = | - | 26 9 |
| x | = | - | 26 9 | ÷ | 1 9 |
| = | - | 26 9 | × | 9 |
| = | - | 26 | × | 1 |
| x | = | - | 26 |
