| ( | 1 10 | + | x | ) | ÷ | ( | 1 | − | x | ) | = | 241 100 |
| 方程两边同时乘以: | ( | 1 | − | x | ) |
| ( | 1 10 | + | x | ) | = | 241 100 | ( | 1 | − | x | ) |
1 10 | + | x | = | 241 100 | ( | 1 | − | x | ) |
1 10 | + | x | = | 241 100 | × | 1 | − | 241 100 | x |
1 10 | + | x | = | 241 100 | − | 241 100 | x |
| x | + | 241 100 | x | = | 241 100 | − | 1 10 |
341 100 | x | = | 241 100 | − | 1 10 |
341 100 | x | = | 231 100 |
| x | = | 231 100 | ÷ | 341 100 |
| = | 231 100 | × | 100 341 |
| = | 21 | × | 1 31 |
| x | = | 21 31 |
