| x | ( | 29 | ÷ | 2 | − | 2 | x | ) | = | ( | 2 | x | − | 4 | ) | ( | 22 | ÷ | 5 | − | x | ) |
| 方程左边 = | x | × | 29 | ÷ | 2 | − | x | × | 2 | x |
| = | x | × | 29 2 | − | x | × | 2 | x |
29 2 | x | − | x | × | 2 | x | = | ( | 2 | x | − | 4 | ) | ( | 22 | ÷ | 5 | − | x | ) |
| 方程右边 = | 2 | x | ( | 22 | ÷ | 5 | − | x | ) | − | 4 | ( | 22 | ÷ | 5 | − | x | ) |
| = | 2 | x | × | 22 | ÷ | 5 | − | 2 | x | x | − | 4 | ( | 22 | ÷ | 5 | − | x | ) |
| = | 44 5 | x | − | 2 | x | x | − | 4 | ( | 22 | ÷ | 5 | − | x | ) |
| = | 44 5 | x | − | 2 | x | x | − | 4 | × | 22 | ÷ | 5 | + | 4 | x |
| = | 44 5 | x | − | 2 | x | x | − | 88 5 | + | 4 | x |
| = | 64 5 | x | − | 2 | x | x | − | 88 5 |
29 2 | x | − | x | × | 2 | x | = | 64 5 | x | − | 2 | x | x | − | 88 5 |
