| 716 | ÷ | ( | x | + | 716 | ) | = | 47 5 |
| 方程两边同时乘以: | ( | x | + | 716 | ) |
| 716 | = | 47 5 | ( | x | + | 716 | ) |
| 716 | = | 47 5 | x | + | 47 5 | × | 716 |
| 716 | = | 47 5 | x | + | 33652 5 |
| - | 47 5 | x | = | 33652 5 | − | 716 |
| - | 47 5 | x | = | 30072 5 |
| - | 30072 5 | = | 47 5 | x |
47 5 | x | = | - | 30072 5 |
| x | = | - | 30072 5 | ÷ | 47 5 |
| = | - | 30072 5 | × | 5 47 |
| = | - | 30072 | × | 1 47 |
| x | = | - | 30072 47 |
