| x | + | ( | 2 | ÷ | 2 | × | x | + | 1 | ) | − | ( | 3 | ÷ | 2 | ) | = | 1 | ÷ | 2 |
| 方程左边 = | x | + | 2 | ÷ | 2 | × | x | + | 1 | − | ( | 3 | ÷ | 2 | ) |
| = | x | + | 1 | x | + | 1 | − | ( | 3 | ÷ | 2 | ) |
| = | 2 | x | + | 1 | − | ( | 3 | ÷ | 2 | ) |
| = | 2 | x | + | 1 | − | 3 | ÷ | 2 |
| = | 2 | x | + | 1 | − | 3 2 |
| = | 2 | x | − | 1 2 |
| 2 | x | − | 1 2 | = | 1 | ÷ | 2 |
| 方程右边 = | 1 2 |
| 2 | x | − | 1 2 | = | 1 2 |
| 2 | x | = | 1 2 | + | 1 2 |
| 2 | x | = | 1 |
| x | = | 1 | ÷ | 2 |
| = | 1 | × | 1 2 |
| x | = | 1 2 |
| x | = | 0.5 |
