2 | x | ÷ | 3 | + | 1 | ÷ | 3 | = | 5 | x | ÷ | 6 | − | 1 | ÷ | 6 | − | 1 |
方程左边 = | 2 3 | x | + | 1 3 |
2 3 | x | + | 1 3 | = | 5 | x | ÷ | 6 | − | 1 | ÷ | 6 | − | 1 |
方程右边 = | 5 6 | x | − | 1 6 | − | 1 |
= | 5 6 | x | − | 7 6 |
2 3 | x | + | 1 3 | = | 5 6 | x | − | 7 6 |
2 3 | x | − | 5 6 | x | = | - | 7 6 | − | 1 3 |
- | 1 6 | x | = | - | 7 6 | − | 1 3 |
- | 1 6 | x | = | - | 3 2 |
3 2 | = | 1 6 | x |
1 6 | x | = | 3 2 |
x | = | 3 2 | ÷ | 1 6 |
= | 3 2 | × | 6 |
= | 3 | × | 3 |
x | = | 9 |
