17 10 | − | 2 | x | ÷ | 3 10 | = | 1 | − | ( | 1 2 | + | 2 | x | ) | ÷ | 3 5 |
| 方程左边 = | 17 10 | − | 20 3 | x |
17 10 | − | 20 3 | x | = | 1 | − | ( | 1 2 | + | 2 | x | ) | ÷ | 3 5 |
| 方程右边 = | 1 | − | 1 2 | × | 5 3 | − | 2 | x | × | 5 3 |
| = | 1 | − | 5 6 | − | 10 3 | x |
| = | 1 6 | − | 10 3 | x |
17 10 | − | 20 3 | x | = | 1 6 | − | 10 3 | x |
| - | 20 3 | x | + | 10 3 | x | = | 1 6 | − | 17 10 |
| - | 10 3 | x | = | 1 6 | − | 17 10 |
| - | 10 3 | x | = | - | 23 15 |
23 15 | = | 10 3 | x |
10 3 | x | = | 23 15 |
| x | = | 23 15 | ÷ | 10 3 |
| = | 23 15 | × | 3 10 |
| = | 23 5 | × | 1 10 |
| x | = | 23 50 |
| x | = | 0.46 |
