| ( | 36 | + | x | ) | ÷ | ( | 96 | + | x | ) | = | 5 | ÷ | 11 |
| 方程两边同时乘以: | ( | 96 | + | x | ) |
| ( | 36 | + | x | ) | = | 5 | ÷ | 11 | × | ( | 96 | + | x | ) |
| 36 | + | x | = | 5 | ÷ | 11 | × | ( | 96 | + | x | ) |
| 36 | + | x | = | 5 | ÷ | 11 | × | 96 | + | 5 | ÷ | 11 | × | x |
| 36 | + | x | = | 480 11 | + | 5 11 | x |
| x | − | 5 11 | x | = | 480 11 | − | 36 |
6 11 | x | = | 480 11 | − | 36 |
6 11 | x | = | 84 11 |
| x | = | 84 11 | ÷ | 6 11 |
| = | 84 11 | × | 11 6 |
| = | 14 | × | 1 |
| x | = | 14 |
