| x | − | ( | 1 | ÷ | 2 | ) | x | − | 50 | = | ( | 6 | ÷ | 11 | ) | x |
| 方程左边 = | x | − | 1 | ÷ | 2 | × | x | − | 50 |
| = | x | − | 1 2 | x | − | 50 |
| = | 1 2 | x | − | 50 |
1 2 | x | − | 50 | = | ( | 6 | ÷ | 11 | ) | x |
| 方程右边 = | 6 | ÷ | 11 | × | x |
| = | 6 11 | x |
1 2 | x | − | 50 | = | 6 11 | x |
1 2 | x | − | 6 11 | x | = | 50 |
| - | 1 22 | x | = | 50 |
| - | 50 | = | 1 22 | x |
1 22 | x | = | - | 50 |
| x | = | - | 50 | ÷ | 1 22 |
| = | - | 50 | × | 22 |
| x | = | - | 1100 |
