| x | ÷ | ( | 2600 | + | x | ) | = | 57 1000 |
| 方程两边同时乘以: | ( | 2600 | + | x | ) |
| x | = | 57 1000 | ( | 2600 | + | x | ) |
| x | = | 57 1000 | × | 2600 | + | 57 1000 | x |
| x | = | 741 5 | + | 57 1000 | x |
| x | − | 57 1000 | x | = | 741 5 |
943 1000 | x | = | 741 5 |
| x | = | 741 5 | ÷ | 943 1000 |
| = | 741 5 | × | 1000 943 |
| = | 741 | × | 200 943 |
| x | = | 148200 943 |
| x | = | 157.158006 |
