| ( | x | − | 24 | ÷ | 54 5 | ) | − | ( | x | ÷ | 12 | ) | = | 1 |
| 方程左边 = | x | − | 24 | ÷ | 54 5 | − | ( | x | ÷ | 12 | ) |
| = | x | − | 20 9 | − | ( | x | ÷ | 12 | ) |
| = | x | − | 20 9 | − | x | ÷ | 12 |
| = | 11 12 | x | − | 20 9 |
11 12 | x | − | 20 9 | = | 1 |
11 12 | x | = | 1 | + | 20 9 |
11 12 | x | = | 29 9 |
| x | = | 29 9 | ÷ | 11 12 |
| = | 29 9 | × | 12 11 |
| = | 29 3 | × | 4 11 |
| x | = | 116 33 |
| x | = | 3.515152 |
