| ( | 576 | + | x | ) | ÷ | ( | 704 | + | 200 | − | x | ) | = | 11 10 |
| 方程两边同时乘以: | ( | 704 | + | 200 | − | x | ) |
| ( | 576 | + | x | ) | = | 11 10 | ( | 704 | + | 200 | − | x | ) |
| 576 | + | x | = | 11 10 | ( | 704 | + | 200 | − | x | ) |

| 576 | + | x | = | 3872 5 | + | 220 | − | 11 10 | x |
| 576 | + | x | = | 4972 5 | − | 11 10 | x |
| x | + | 11 10 | x | = | 4972 5 | − | 576 |
