| 2600 | x | ÷ | ( | 2600 | x | + | 2600 | ) | = | 27 500 |
| 方程两边同时乘以: | ( | 2600 | x | + | 2600 | ) |
| 2600 | x | = | 27 500 | ( | 2600 | x | + | 2600 | ) |
| 2600 | x | = | 27 500 | × | 2600 | x | + | 27 500 | × | 2600 |
| 2600 | x | = | 702 5 | x | + | 702 5 |
| 2600 | x | − | 702 5 | x | = | 702 5 |
12298 5 | x | = | 702 5 |
| x | = | 702 5 | ÷ | 12298 5 |
| = | 702 5 | × | 5 12298 |
| = | 27 | × | 1 473 |
