2 | ÷ | 3 | × | x | − | 1 | = | 5 | ÷ | 4 | × | x | + | 2 | − | 1 |
方程左边 = | 2 3 | x | − | 1 |
2 3 | x | − | 1 | = | 5 | ÷ | 4 | × | x | + | 2 | − | 1 |
方程右边 = | 5 4 | x | + | 2 | − | 1 |
= | 5 4 | x | + | 1 |
2 3 | x | − | 1 | = | 5 4 | x | + | 1 |
2 3 | x | − | 5 4 | x | = | 1 | + | 1 |
- | 7 12 | x | = | 1 | + | 1 |
- | 7 12 | x | = | 2 |
- | 2 | = | 7 12 | x |
7 12 | x | = | - | 2 |
x | = | - | 2 | ÷ | 7 12 |
= | - | 2 | × | 12 7 |
x | = | - | 24 7 |
x | = | - 3.428571 |
