| 3 | ( | ( | 3 | ( | x | − | 2 | ) | + | 5 | ) | − | 6 | ) | + | 3 | = | x | − | 106 |
| 方程左边 = | 3 | ( | 3 | ( | x | − | 2 | ) | + | 5 | ) | − | 3 | × | 6 | + | 3 |
| = | 3 | ( | 3 | ( | x | − | 2 | ) | + | 5 | ) | − | 18 | + | 3 |
| = | 3 | ( | 3 | ( | x | − | 2 | ) | + | 5 | ) | − | 15 |
| = | 3 | × | 3 | ( | x | − | 2 | ) | + | 3 | × | 5 | − | 15 |
| = | 9 | ( | x | − | 2 | ) | + | 15 | − | 15 |
| = | 9 | ( | x | − | 2 | ) | + | 0 |
| = | 9 | x | − | 9 | × | 2 |
| = | 9 | x | − | 18 |
| 9 | x | − | 18 | = | x | − | 106 |
| 9 | x | − | x | = | - | 106 | + | 18 |
| 8 | x | = | - | 106 | + | 18 |
| 8 | x | = | - | 88 |
| x | = | - | 88 | ÷ | 8 |
| = | - | 88 | × | 1 8 |
| = | - | 11 | × | 1 |
| x | = | - | 11 |
