27 5 | ÷ | ( | 3 5 | + | x | ) | = | 97 10 | ÷ | ( | 1 | + | x | ) |
| 方程两边同时乘以: | ( | 3 5 | + | x | ) | , | ( | 1 | + | x | ) |
27 5 | ( | 1 | + | x | ) | = | 97 10 | ( | 3 5 | + | x | ) |
27 5 | × | 1 | + | 27 5 | x | = | 97 10 | ( | 3 5 | + | x | ) |
27 5 | × | 1 | + | 27 5 | x | = | 97 10 | × | 3 5 | + | 97 10 | x |
27 5 | + | 27 5 | x | = | 291 50 | + | 97 10 | x |
27 5 | x | − | 97 10 | x | = | 291 50 | − | 27 5 |
| - | 43 10 | x | = | 291 50 | − | 27 5 |
| - | 43 10 | x | = | 21 50 |
| - | 21 50 | = | 43 10 | x |
43 10 | x | = | - | 21 50 |
| x | = | - | 21 50 | ÷ | 43 10 |
| = | - | 21 50 | × | 10 43 |
| = | - | 21 5 | × | 1 43 |
