| ( | x | − | 10 | ÷ | 3 | ) | ( | x | − | 8 | ÷ | 3 | ) | = | ( | 11 | ÷ | 6 | ) | ( | 11 | ÷ | 6 | ) | × | 5 2 |
| 方程左边 = | x | ( | x | − | 8 | ÷ | 3 | ) | − | 10 | ÷ | 3 | × | ( | x | − | 8 | ÷ | 3 | ) |
| = | x | ( | x | − | 8 | ÷ | 3 | ) | − | 10 3 | ( | x | − | 8 | ÷ | 3 | ) |
| = | x | x | − | x | × | 8 | ÷ | 3 | − | 10 3 | ( | x | − | 8 | ÷ | 3 | ) |
| = | x | x | − | x | × | 8 3 | − | 10 3 | ( | x | − | 8 | ÷ | 3 | ) |
| = | x | x | − | 8 3 | x | − | 10 3 | x | + | 10 3 | × | 8 | ÷ | 3 |
| = | x | x | − | 8 3 | x | − | 10 3 | x | + | 80 9 |
| = | x | x | − | 6 | x | + | 80 9 |
| x | x | − | 6 | x | + | 80 9 | = | ( | 11 | ÷ | 6 | ) | ( | 11 | ÷ | 6 | ) | × | 5 2 |
| 方程右边 = | 11 | ÷ | 6 | × | ( | 11 | ÷ | 6 | ) | × | 5 2 |
| = | 55 12 | ( | 11 | ÷ | 6 | ) |
| = | 55 12 | × | 11 | ÷ | 6 |
| = | 605 72 |
| x | x | − | 6 | x | + | 80 9 | = | 605 72 |
