| ( | x | − | 1 | ) | ÷ | 6 | = | ( | x | − | 2 | ) | ÷ | 5 |
| 方程左边 = | x | × | 1 6 | − | 1 | × | 1 6 |
| = | x | × | 1 6 | − | 1 6 |
1 6 | x | − | 1 6 | = | ( | x | − | 2 | ) | ÷ | 5 |
| 方程右边 = | x | × | 1 5 | − | 2 | × | 1 5 |
| = | x | × | 1 5 | − | 2 5 |
1 6 | x | − | 1 6 | = | 1 5 | x | − | 2 5 |
1 6 | x | − | 1 5 | x | = | - | 2 5 | + | 1 6 |
| - | 1 30 | x | = | - | 2 5 | + | 1 6 |
| - | 1 30 | x | = | - | 7 30 |
7 30 | = | 1 30 | x |
1 30 | x | = | 7 30 |
| x | = | 7 30 | ÷ | 1 30 |
| = | 7 30 | × | 30 |
| = | 7 | × | 1 |
| x | = | 7 |
