x | ÷ | ( | x | − | 1 | ) | − | 1 | = | 3 | ÷ | ( | x | − | 1 | ) | × | ( | x | + | 2 | ) |
方程两边同时乘以: | ( | x | − | 1 | ) |
x | − | 1 | ( | x | − | 1 | ) | = | 3 | ( | x | + | 2 | ) |
x | − | 1 | x | + | 1 | × | 1 | = | 3 | ( | x | + | 2 | ) |
x | − | 1 | x | + | 1 | × | 1 | = | 3 | x | + | 3 | × | 2 |
x | − | 1 | x | + | 1 | = | 3 | x | + | 6 |
0 | x | + | 1 | = | 3 | x | + | 6 |
- | 3 | x | = | 6 | − | 1 |
- | 3 | x | = | 5 |
- | 5 | = | 3 | x |
3 | x | = | - | 5 |
x | = | - | 5 | ÷ | 3 |
= | - | 5 | × | 1 3 |
x | = | - | 5 3 |
x | = | - 1.666667 |
