| 6 | ( | 3 | ÷ | 2 | × | x | − | 5 | ) | − | x | × | 6 | = | 6 | − | ( | 2 | ÷ | 1 | × | x | + | 1 | ) |
| 方程左边 = | 6 | × | 3 | ÷ | 2 | × | x | − | 6 | × | 5 | − | 6 | x |
| = | 9 | x | − | 30 | − | 6 | x |
| = | 3 | x | − | 30 |
| 3 | x | − | 30 | = | 6 | − | ( | 2 | ÷ | 1 | × | x | + | 1 | ) |
| 方程右边 = | 6 | − | 2 | ÷ | 1 | × | x | − | 1 |
| = | 6 | − | 2 | x | − | 1 |
| = | 5 | − | 2 | x |
| 3 | x | − | 30 | = | 5 | − | 2 | x |
| 3 | x | + | 2 | x | = | 5 | + | 30 |
| 5 | x | = | 5 | + | 30 |
| 5 | x | = | 35 |
| x | = | 35 | ÷ | 5 |
| = | 35 | × | 1 5 |
| = | 7 | × | 1 |
| x | = | 7 |
