方程左边 = | 1 3 | x | + | 1 2 | ( | 132 | − | x | ) |
1 3 | x | + | 1 2 | ( | 132 | − | x | ) | = | 59 |
方程左边 = | 1 3 | x | + | 1 2 | × | 132 | − | 1 2 | x |
= | 1 3 | x | + | 66 | − | 1 2 | x |
= | - | 1 6 | x | + | 66 |
- | 1 6 | x | + | 66 | = | 59 |
- | 1 6 | x | = | 59 | − | 66 |
- | 1 6 | x | = | - | 7 |
7 | = | 1 6 | x |
1 6 | x | = | 7 |
x | = | 7 | ÷ | 1 6 |
= | 7 | × | 6 |
