6 | − | 12 | ÷ | 5 | × | x | = | 3 | ÷ | 2 | − | 3 | ÷ | 10 | × | x |
方程左边 = | 6 | − | 12 5 | x |
6 | − | 12 5 | x | = | 3 | ÷ | 2 | − | 3 | ÷ | 10 | × | x |
方程右边 = | 3 2 | − | 3 10 | x |
6 | − | 12 5 | x | = | 3 2 | − | 3 10 | x |
- | 12 5 | x | + | 3 10 | x | = | 3 2 | − | 6 |
- | 21 10 | x | = | 3 2 | − | 6 |
- | 21 10 | x | = | - | 9 2 |
9 2 | = | 21 10 | x |
21 10 | x | = | 9 2 |
x | = | 9 2 | ÷ | 21 10 |
= | 9 2 | × | 10 21 |
= | 3 | × | 5 7 |
x | = | 15 7 |
x | = | 2.142857 |
