9 5 | − | 8 | x | ÷ | 6 5 | − | 13 10 | − | 3 | x | ÷ | 6 5 | = | 5 | x | − | 2 5 | ÷ | 3 10 |
| 方程左边 = | 9 5 | − | 20 3 | x | − | 13 10 | − | 5 2 | x |
| = | 1 2 | − | 55 6 | x |
1 2 | − | 55 6 | x | = | 5 | x | − | 2 5 | ÷ | 3 10 |
| 方程右边 = | 5 | x | − | 4 3 |
1 2 | − | 55 6 | x | = | 5 | x | − | 4 3 |
| - | 55 6 | x | − | 5 | x | = | - | 4 3 | − | 1 2 |
| - | 85 6 | x | = | - | 4 3 | − | 1 2 |
| - | 85 6 | x | = | - | 11 6 |
11 6 | = | 85 6 | x |
85 6 | x | = | 11 6 |
| x | = | 11 6 | ÷ | 85 6 |
| = | 11 6 | × | 6 85 |
| = | 11 | × | 1 85 |
| x | = | 11 85 |
| x | = | 0.129412 |
