( | x | + | 1 | ) | ÷ | 4 | − | 1 | = | ( | 2 | x | − | 1 | ) | ÷ | 6 |
方程左边 = | x | × | 1 4 | + | 1 | × | 1 4 | − | 1 |
= | x | × | 1 4 | + | 1 4 | − | 1 |
= | 1 4 | x | − | 3 4 |
1 4 | x | − | 3 4 | = | ( | 2 | x | − | 1 | ) | ÷ | 6 |
方程右边 = | 2 | x | × | 1 6 | − | 1 | × | 1 6 |
= | 1 3 | x | − | 1 6 |
1 4 | x | − | 3 4 | = | 1 3 | x | − | 1 6 |
1 4 | x | − | 1 3 | x | = | - | 1 6 | + | 3 4 |
- | 1 12 | x | = | - | 1 6 | + | 3 4 |
- | 1 12 | x | = | 7 12 |
- | 7 12 | = | 1 12 | x |
1 12 | x | = | - | 7 12 |
x | = | - | 7 12 | ÷ | 1 12 |
= | - | 7 12 | × | 12 |
= | - | 7 | × | 1 |
x | = | - | 7 |
