| 1 | − | 3 | x | ÷ | 5 | = | ( | 5 | x | − | 1 | ) | ÷ | 9 |
| 方程左边 = | 1 | − | 3 5 | x |
| 1 | − | 3 5 | x | = | ( | 5 | x | − | 1 | ) | ÷ | 9 |
| 方程右边 = | 5 | x | × | 1 9 | − | 1 | × | 1 9 |
| = | 5 9 | x | − | 1 9 |
| 1 | − | 3 5 | x | = | 5 9 | x | − | 1 9 |
| - | 3 5 | x | − | 5 9 | x | = | - | 1 9 | − | 1 |
| - | 52 45 | x | = | - | 1 9 | − | 1 |
| - | 52 45 | x | = | - | 10 9 |
10 9 | = | 52 45 | x |
52 45 | x | = | 10 9 |
| x | = | 10 9 | ÷ | 52 45 |
| = | 10 9 | × | 45 52 |
| = | 5 | × | 5 26 |
| x | = | 25 26 |
| x | = | 0.961538 |
