( | ( | 1 10 | − | 1 5 | x | ) | ÷ | 3 10 | ) | − | 1 | = | ( | 7 10 | − | x | ) | ÷ | 2 5 |
方程左边 = | ( | 1 10 | − | 1 5 | x | ) | ÷ | 3 10 | − | 1 |
= | 1 10 | × | 10 3 | − | 1 5 | x | × | 10 3 | − | 1 |
= | 1 3 | − | 2 3 | x | − | 1 |
= | - | 2 3 | − | 2 3 | x |
- | 2 3 | − | 2 3 | x | = | ( | 7 10 | − | x | ) | ÷ | 2 5 |
方程右边 = | 7 10 | × | 5 2 | − | x | × | 5 2 |
= | 7 4 | − | x | × | 5 2 |
- | 2 3 | − | 2 3 | x | = | 7 4 | − | 5 2 | x |
- | 2 3 | x | + | 5 2 | x | = | 7 4 | + | 2 3 |
11 6 | x | = | 7 4 | + | 2 3 |
11 6 | x | = | 29 12 |
x | = | 29 12 | ÷ | 11 6 |
= | 29 12 | × | 6 11 |
= | 29 2 | × | 1 11 |
x | = | 29 22 |
x | = | 1.318182 |
