( | 2 | x | − | 1 | ) | ÷ | 3 | − | ( | x | + | 5 | ) | ÷ | 6 | = | 2 | x | − | 1 |
方程左边 = | 2 | x | × | 1 3 | − | 1 | × | 1 3 | − | ( | x | + | 5 | ) | × | 1 6 |
= | 2 3 | x | − | 1 3 | − | ( | x | + | 5 | ) | × | 1 6 |
= | 2 3 | x | − | 1 3 | − | x | × | 1 6 | − | 5 | × | 1 6 |
= | 2 3 | x | − | 1 3 | − | x | × | 1 6 | − | 5 6 |
= | 1 2 | x | − | 7 6 |
1 2 | x | − | 7 6 | = | 2 | x | − | 1 |
1 2 | x | − | 2 | x | = | - | 1 | + | 7 6 |
- | 3 2 | x | = | - | 1 | + | 7 6 |
- | 3 2 | x | = | 1 6 |
- | 1 6 | = | 3 2 | x |
3 2 | x | = | - | 1 6 |
x | = | - | 1 6 | ÷ | 3 2 |
