| 方程左边 = | 8 | × | 2 | x | − | 8 | × | 1 | − | 6 | ( | 3 | x | − | 1 | ) |
| = | 16 | x | − | 8 | − | 6 | ( | 3 | x | − | 1 | ) |
| = | 16 | x | − | 8 | − | 6 | × | 3 | x | + | 6 | × | 1 |
| = | 16 | x | − | 8 | − | 18 | x | + | 6 |
| = | - | 2 | x | − | 2 |
| - | 2 | x | − | 2 | = | - | 1 |
| - | 2 | x | = | - | 1 | + | 2 |
| - | 2 | x | = | 1 |
| - | 1 | = | 2 | x |
| 2 | x | = | - | 1 |
| x | = | - | 1 | ÷ | 2 |
| = | - | 1 | × | 1 2 |
| x | = | - | 1 2 |
| x | = | - 0.5 |
