| 2600 | x | ÷ | ( | 2600 | x | + | 2600 | ) | = | 57 1000 |
| 方程两边同时乘以: | ( | 2600 | x | + | 2600 | ) |
| 2600 | x | = | 57 1000 | ( | 2600 | x | + | 2600 | ) |
| 2600 | x | = | 57 1000 | × | 2600 | x | + | 57 1000 | × | 2600 |
| 2600 | x | = | 741 5 | x | + | 741 5 |
| 2600 | x | − | 741 5 | x | = | 741 5 |
12259 5 | x | = | 741 5 |
| x | = | 741 5 | ÷ | 12259 5 |
| = | 741 5 | × | 5 12259 |
| = | 57 | × | 1 943 |
