| x | − | ( | 1 | ÷ | 3 | × | x | + | 2 | ) | − | ( | 1 | ÷ | 2 | × | x | + | 2 | ) | = | 10 |
| 方程左边 = | x | − | 1 | ÷ | 3 | × | x | − | 2 | − | ( | 1 | ÷ | 2 | × | x | + | 2 | ) |
| = | x | − | 1 3 | x | − | 2 | − | ( | 1 | ÷ | 2 | × | x | + | 2 | ) |
| = | 2 3 | x | − | 2 | − | ( | 1 | ÷ | 2 | × | x | + | 2 | ) |
| = | 2 3 | x | − | 2 | − | 1 | ÷ | 2 | × | x | − | 2 |
| = | 2 3 | x | − | 2 | − | 1 2 | x | − | 2 |
| = | 1 6 | x | − | 4 |
1 6 | x | − | 4 | = | 10 |
1 6 | x | = | 10 | + | 4 |
1 6 | x | = | 14 |
| x | = | 14 | ÷ | 1 6 |
| = | 14 | × | 6 |
| x | = | 84 |
