| x | ÷ | ( | 1 | + | x | ) | = | 4369 50000 |
| 方程两边同时乘以: | ( | 1 | + | x | ) |
| x | = | 4369 50000 | ( | 1 | + | x | ) |
| x | = | 4369 50000 | × | 1 | + | 4369 50000 | x |
| x | = | 4369 50000 | + | 4369 50000 | x |
| x | − | 4369 50000 | x | = | 4369 50000 |
45631 50000 | x | = | 4369 50000 |
| x | = | 4369 50000 | ÷ | 45631 50000 |
| = | 4369 50000 | × | 50000 45631 |
| = | 4369 | × | 1 45631 |
| x | = | 4369 45631 |
| x | = | 0.095746 |
