| x | − | ( | ( | ( | 2 | ÷ | 3 | ) | x | + | 12 | ) | + | ( | ( | 1 | ÷ | 6 | ) | x | − | 3 | ) | ) | = | 10 |
| 方程左边 = | x | − | ( | ( | 2 | ÷ | 3 | ) | x | + | 12 | ) | − | ( | ( | 1 | ÷ | 6 | ) | x | − | 3 | ) |
| = | x | − | ( | 2 | ÷ | 3 | ) | x | − | 12 | − | ( | ( | 1 | ÷ | 6 | ) | x | − | 3 | ) |
| = | x | − | 2 | ÷ | 3 | × | x | − | 12 | − | ( | ( | 1 | ÷ | 6 | ) | x | − | 3 | ) |
| = | x | − | 2 3 | x | − | 12 | − | ( | ( | 1 | ÷ | 6 | ) | x | − | 3 | ) |
| = | 1 3 | x | − | 12 | − | ( | ( | 1 | ÷ | 6 | ) | x | − | 3 | ) |
| = | 1 3 | x | − | 12 | − | ( | 1 | ÷ | 6 | ) | x | + | 3 |
| = | 1 3 | x | − | 9 | − | ( | 1 | ÷ | 6 | ) | x |
| = | 1 3 | x | − | 9 | − | 1 | ÷ | 6 | × | x |
| = | 1 3 | x | − | 9 | − | 1 6 | x |
| = | 1 6 | x | − | 9 |
1 6 | x | − | 9 | = | 10 |
1 6 | x | = | 10 | + | 9 |
1 6 | x | = | 19 |
| x | = | 19 | ÷ | 1 6 |
| = | 19 | × | 6 |
| x | = | 114 |
