| 方程右边 = | 97 100 | x | − | 97 100 | × | 1 |
| = | 97 100 | x | − | 97 100 |
9 10 | + | 3 2 | x | = | 97 100 | x | − | 97 100 |
3 2 | x | − | 97 100 | x | = | - | 97 100 | − | 9 10 |
53 100 | x | = | - | 97 100 | − | 9 10 |
53 100 | x | = | - | 187 100 |
| x | = | - | 187 100 | ÷ | 53 100 |
| = | - | 187 100 | × | 100 53 |
| = | - | 187 | × | 1 53 |
| x | = | - | 187 53 |
