576 5 | ÷ | ( | X | − | 576 5 | ) | = | 30 100 |
| 方程两边同时乘以: | ( | X | − | 576 5 | ) |
576 5 | = | 30 100 | ( | X | − | 576 5 | ) |
576 5 | = | 30 100 | X | − | 30 100 | × | 576 5 |
576 5 | = | 30 100 | X | − | 864 25 |
| - | 30 100 | X | = | - | 864 25 | − | 576 5 |
| - | 30 100 | X | = | - | 3744 25 |
3744 25 | = | 30 100 | X |
30 100 | X | = | 3744 25 |
| X | = | 3744 25 | ÷ | 30 100 |
| = | 3744 25 | × | 100 30 |
| = | 624 | × | 4 5 |
| X | = | 2496 5 |
| X | = | 499.2 |
