| 2600 | x | ÷ | ( | 2600 | x | + | 2600 | ) | = | 53 1000 |
| 方程两边同时乘以: | ( | 2600 | x | + | 2600 | ) |
| 2600 | x | = | 53 1000 | ( | 2600 | x | + | 2600 | ) |
| 2600 | x | = | 53 1000 | × | 2600 | x | + | 53 1000 | × | 2600 |
| 2600 | x | = | 689 5 | x | + | 689 5 |
| 2600 | x | − | 689 5 | x | = | 689 5 |
12311 5 | x | = | 689 5 |
| x | = | 689 5 | ÷ | 12311 5 |
| = | 689 5 | × | 5 12311 |
| = | 53 | × | 1 947 |
