( | 1 | ÷ | 2 | ) | − | ( | x | − | 1 | ) | ÷ | 3 | = | 1 |
方程左边 = | 1 | ÷ | 2 | − | ( | x | − | 1 | ) | × | 1 3 |
= | 1 2 | − | ( | x | − | 1 | ) | × | 1 3 |
= | 1 2 | − | x | × | 1 3 | + | 1 | × | 1 3 |
= | 1 2 | − | x | × | 1 3 | + | 1 3 |
= | 5 6 | − | 1 3 | x |
5 6 | − | 1 3 | x | = | 1 |
- | 1 3 | x | = | 1 | − | 5 6 |
- | 1 3 | x | = | 1 6 |
- | 1 6 | = | 1 3 | x |
1 3 | x | = | - | 1 6 |
x | = | - | 1 6 | ÷ | 1 3 |
= | - | 1 6 | × | 3 |
= | - | 1 2 | × | 1 |
x | = | - | 1 2 |
x | = | - 0.5 |
