| ( | 2 | ÷ | 3 | ) | − | 8 | x | = | 3 | − | ( | 1 2 | x | ) |
| 方程左边 = | 2 | ÷ | 3 | − | 8 | x |
| = | 2 3 | − | 8 | x |
2 3 | − | 8 | x | = | 3 | − | ( | 1 2 | x | ) |
| 方程右边 = | 3 | − | 1 2 | x |
2 3 | − | 8 | x | = | 3 | − | 1 2 | x |
| - | 8 | x | + | 1 2 | x | = | 3 | − | 2 3 |
| - | 15 2 | x | = | 3 | − | 2 3 |
| - | 15 2 | x | = | 7 3 |
| - | 7 3 | = | 15 2 | x |
15 2 | x | = | - | 7 3 |
| x | = | - | 7 3 | ÷ | 15 2 |
| = | - | 7 3 | × | 2 15 |
| x | = | - | 14 45 |
| x | = | - 0.311111 |
