x | ÷ | 2 | − | 5 | x | + | 11 | = | 1 | + | 2 | x | − | 4 | ÷ | 3 |
方程左边 = | - | 9 2 | x | + | 11 |
- | 9 2 | x | + | 11 | = | 1 | + | 2 | x | − | 4 | ÷ | 3 |
方程右边 = | 1 | + | 2 | x | − | 4 3 |
= | - | 1 3 | + | 2 | x |
- | 9 2 | x | + | 11 | = | - | 1 3 | + | 2 | x |
- | 9 2 | x | − | 2 | x | = | - | 1 3 | − | 11 |
- | 13 2 | x | = | - | 1 3 | − | 11 |
- | 13 2 | x | = | - | 34 3 |
34 3 | = | 13 2 | x |
13 2 | x | = | 34 3 |
x | = | 34 3 | ÷ | 13 2 |
= | 34 3 | × | 2 13 |
x | = | 68 39 |
x | = | 1.74359 |
