| 2600 | x | ÷ | ( | 2600 | x | + | 2600 | ) | = | 11 200 |
| 方程两边同时乘以: | ( | 2600 | x | + | 2600 | ) |
| 2600 | x | = | 11 200 | ( | 2600 | x | + | 2600 | ) |
| 2600 | x | = | 11 200 | × | 2600 | x | + | 11 200 | × | 2600 |
| 2600 | x | = | 143 | x | + | 143 |
| 2600 | x | − | 143 | x | = | 143 |
| 2457 | x | = | 143 |
| x | = | 143 | ÷ | 2457 |
| = | 143 | × | 1 2457 |
| x | = | 143 2457 |
| x | = | 11 189 |
| x | = | 0.058201 |
