| 方程左边 = | X | − | X | × | 97 100 | − | ( | X | × | 97 100 | × | 3 50 | ) |
| = | 3 100 | X | − | ( | X | × | 97 100 | × | 3 50 | ) |
| = | 3 100 | X | − | X | × | 97 100 | × | 3 50 |
| = | 3 100 | X | − | X | × | 291 5000 |
| = | - | 141 5000 | X |
| - | 141 5000 | X | = | 100000 |
| - | 100000 | = | 141 5000 | X |
141 5000 | X | = | - | 100000 |
| X | = | - | 100000 | ÷ | 141 5000 |
| = | - | 100000 | × | 5000 141 |
| X | = | - | 500000000 141 |
