| X | ÷ | ( | 2259887 2 | + | X | ) | = | 2 5 |
| 方程两边同时乘以: | ( | 2259887 2 | + | X | ) |
| X | = | 2 5 | ( | 2259887 2 | + | X | ) |
| X | = | 2 5 | × | 2259887 2 | + | 2 5 | X |
| X | = | 2259887 5 | + | 2 5 | X |
| X | − | 2 5 | X | = | 2259887 5 |
3 5 | X | = | 2259887 5 |
| X | = | 2259887 5 | ÷ | 3 5 |
| = | 2259887 5 | × | 5 3 |
| = | 2259887 | × | 1 3 |
| X | = | 2259887 3 |
| X | = | 753295.666667 |
