| ( | 1001 1000 | + | 71 100 | X | ) | ÷ | ( | X | + | 1 | ) | = | 0 |
| 方程两边同时乘以: | ( | X | + | 1 | ) |
| ( | 1001 1000 | + | 71 100 | X | ) | = | 0 |
1001 1000 | + | 71 100 | X | = | 0 |

71 100 | X | = | - | 1001 1000 |
| X | = | - | 1001 1000 | ÷ | 71 100 |
| = | - | 1001 1000 | × | 100 71 |
| = | - | 1001 10 | × | 1 71 |
