2 25 | = | x | ÷ | ( | x | + | 2 5 | ) |
| 方程两边同时乘以: | ( | x | + | 2 5 | ) |
2 25 | ( | x | + | 2 5 | ) | = | x |
2 25 | x | + | 2 25 | × | 2 5 | = | x |
2 25 | x | + | 4 125 | = | x |
2 25 | x | − | x | = | - | 4 125 |
| - | 23 25 | x | = | - | 4 125 |
4 125 | = | 23 25 | x |
23 25 | x | = | 4 125 |
| x | = | 4 125 | ÷ | 23 25 |
| = | 4 125 | × | 25 23 |
| = | 4 5 | × | 1 23 |
| x | = | 4 115 |
| x | = | 0.034783 |
