| ( | 127 10 | − | x | ) | ÷ | x | = | 59 100 |
| 方程两边同时乘以: | x |
| ( | 127 10 | − | x | ) | = | 59 100 | x |
127 10 | − | x | = | 59 100 | x |
| - | x | − | 59 100 | x | = | - | 127 10 |
| - | 159 100 | x | = | - | 127 10 |
127 10 | = | 159 100 | x |
159 100 | x | = | 127 10 |
| x | = | 127 10 | ÷ | 159 100 |
| = | 127 10 | × | 100 159 |
| = | 127 | × | 10 159 |
| x | = | 1270 159 |
