4 | ÷ | 3 | − | 8 | x | = | 3 | − | ( | 11 | ÷ | 2 | ) | x |
方程左边 = | 4 3 | − | 8 | x |
4 3 | − | 8 | x | = | 3 | − | ( | 11 | ÷ | 2 | ) | x |
方程右边 = | 3 | − | 11 | ÷ | 2 | × | x |
= | 3 | − | 11 2 | x |
4 3 | − | 8 | x | = | 3 | − | 11 2 | x |
- | 8 | x | + | 11 2 | x | = | 3 | − | 4 3 |
- | 5 2 | x | = | 3 | − | 4 3 |
- | 5 2 | x | = | 5 3 |
- | 5 3 | = | 5 2 | x |
5 2 | x | = | - | 5 3 |
x | = | - | 5 3 | ÷ | 5 2 |
= | - | 5 3 | × | 2 5 |
= | - | 1 3 | × | 2 |
x | = | - | 2 3 |
x | = | - 0.666667 |
