101 2500 | x | + | 41 400 | ( | 10000 | − | x | ) | = | 475 |
| 方程左边 = | 101 2500 | x | + | 41 400 | × | 10000 | − | 41 400 | x |
| = | 101 2500 | x | + | 1025 | − | 41 400 | x |
| = | - | 621 10000 | x | + | 1025 |
| - | 621 10000 | x | + | 1025 | = | 475 |
| - | 621 10000 | x | = | 475 | − | 1025 |
| - | 621 10000 | x | = | - | 550 |
| 550 | = | 621 10000 | x |
621 10000 | x | = | 550 |
| x | = | 550 | ÷ | 621 10000 |
| = | 550 | × | 10000 621 |
| x | = | 5500000 621 |
| x | = | 8856.68277 |
