1 10 | = | 3 5 | x | ÷ | ( | 1 | − | 3 5 | x | ) |
| 方程两边同时乘以: | ( | 1 | − | 3 5 | x | ) |
1 10 | ( | 1 | − | 3 5 | x | ) | = | 3 5 | x |
1 10 | × | 1 | − | 1 10 | × | 3 5 | x | = | 3 5 | x |
1 10 | − | 3 50 | x | = | 3 5 | x |
| - | 3 50 | x | − | 3 5 | x | = | - | 1 10 |
| - | 33 50 | x | = | - | 1 10 |
1 10 | = | 33 50 | x |
33 50 | x | = | 1 10 |
| x | = | 1 10 | ÷ | 33 50 |
| = | 1 10 | × | 50 33 |
| = | 1 | × | 5 33 |
