| 方程左边 = | 3 2 | ( | x | − | 5 | ) |
3 2 | ( | x | − | 5 | ) | = | 5 | ÷ | 7 | × | x | − | 5 |
| 方程左边 = | 3 2 | x | − | 3 2 | × | 5 |
| = | 3 2 | x | − | 15 2 |
3 2 | x | − | 15 2 | = | 5 | ÷ | 7 | × | x | − | 5 |
| 方程右边 = | 5 7 | x | − | 5 |
3 2 | x | − | 15 2 | = | 5 7 | x | − | 5 |
3 2 | x | − | 5 7 | x | = | - | 5 | + | 15 2 |
11 14 | x | = | - | 5 | + | 15 2 |
11 14 | x | = | 5 2 |
| x | = | 5 2 | ÷ | 11 14 |
| = | 5 2 | × | 14 11 |
