864 25 | ( | 263 200 | − | x | ) | = | 136 25 | ( | x | − | 653 500 | ) |
| 方程左边 = | 864 25 | × | 263 200 | − | 864 25 | x |
| = | 28404 625 | − | 864 25 | x |
28404 625 | − | 864 25 | x | = | 136 25 | ( | x | − | 653 500 | ) |
| 方程右边 = | 136 25 | x | − | 136 25 | × | 653 500 |
| = | 136 25 | x | − | 22202 3125 |
28404 625 | − | 864 25 | x | = | 136 25 | x | − | 22202 3125 |
| - | 864 25 | x | − | 136 25 | x | = | - | 22202 3125 | − | 28404 625 |
| - | 40 | x | = | - | 22202 3125 | − | 28404 625 |
| - | 40 | x | = | - | 164222 3125 |
164222 3125 | = | 40 | x |
| 40 | x | = | 164222 3125 |
| x | = | 164222 3125 | ÷ | 40 |
| = | 164222 3125 | × | 1 40 |
| = | 82111 3125 | × | 1 20 |
