10 | ÷ | x | + | ( | 1 | ÷ | 40 | + | 1 | ÷ | x | ) | = | 1 |
方程两边同时乘以: | x |
10 | + | ( | 1 | ÷ | 40 | + | 1 | ÷ | x | ) | x | = | 1 | x |
10 | + | 1 | ÷ | 40 | × | x | + | 1 | ÷ | x | × | x | = | 1 | x |
10 | + | 1 40 | x | + | 1 | ÷ | x | × | x | = | 1 | x |
1 40 | x | − | 1 | x | = | - | 10 | − | 1 | ÷ | 1 | × | 1 |
1 40 | x | − | 1 | x | = | - | 10 | − | 1 |
- | 39 40 | x | = | - | 10 | − | 1 |
- | 39 40 | x | = | - | 11 |
11 | = | 39 40 | x |
39 40 | x | = | 11 |
x | = | 11 | ÷ | 39 40 |
= | 11 | × | 40 39 |
x | = | 440 39 |
