方程两边同时乘以: | x |
2 | − | 1 | x | = | 2 | ( | 2 | ÷ | x | − | 1 | − | 6 | ) | x |
2 | − | 1 | x | = | 2 | × | 2 | ÷ | x | × | x | − | 2 | × | 1 | x | − | 2 | × | 6 | x |
2 | − | 1 | x | = | 4 | ÷ | x | × | x | − | 2 | x | − | 12 | x |
2 | − | 1 | x | = | 4 | ÷ | x | × | x | − | 14 | x |
- | 1 | x | + | 14 | x | = | 4 | ÷ | 1 | × | 1 | − | 2 |
- | 1 | x | + | 14 | x | = | 4 | − | 2 |
13 | x | = | 4 | − | 2 |
13 | x | = | 2 |
x | = | 2 | ÷ | 13 |
= | 2 | × | 1 13 |
x | = | 2 13 |
