| ( | 4481 | − | x | ) | ÷ | ( | 3293 | + | x | ) | = | 6 5 |
| 方程两边同时乘以: | ( | 3293 | + | x | ) |
| ( | 4481 | − | x | ) | = | 6 5 | ( | 3293 | + | x | ) |
| 4481 | − | x | = | 6 5 | ( | 3293 | + | x | ) |
| 4481 | − | x | = | 6 5 | × | 3293 | + | 6 5 | x |
| 4481 | − | x | = | 19758 5 | + | 6 5 | x |
| - | x | − | 6 5 | x | = | 19758 5 | − | 4481 |
| - | 11 5 | x | = | 19758 5 | − | 4481 |
| - | 11 5 | x | = | - | 2647 5 |
2647 5 | = | 11 5 | x |
11 5 | x | = | 2647 5 |
| x | = | 2647 5 | ÷ | 11 5 |
| = | 2647 5 | × | 5 11 |
| = | 2647 | × | 1 11 |
