| x | ÷ | 127 1000 | = | ( | x | − | 18 | ) | ÷ | 73 1000 |
| 方程右边 = | x | × | 1000 73 | − | 18 | × | 1000 73 |
| = | x | × | 1000 73 | − | 18000 73 |
1000 127 | x | = | 1000 73 | x | − | 18000 73 |
1000 127 | x | − | 1000 73 | x | = | - | 18000 73 |
| - | 54000 9271 | x | = | - | 18000 73 |
18000 73 | = | 54000 9271 | x |
54000 9271 | x | = | 18000 73 |
| x | = | 18000 73 | ÷ | 54000 9271 |
| = | 18000 73 | × | 9271 54000 |
| = | 1 | × | 127 3 |
| x | = | 127 3 |
| x | = | 42.333333 |
