| 8 | + | 10 | ( | 6 | − | 11 | x | ) | = | - | 3 | ( | 18 | − | 2 | x | ) | + | 6 | x |
| 方程左边 = | 8 | + | 10 | × | 6 | − | 10 | × | 11 | x |
| = | 8 | + | 60 | − | 110 | x |
| = | 68 | − | 110 | x |
| 68 | − | 110 | x | = | - | 3 | ( | 18 | − | 2 | x | ) | + | 6 | x |
| 方程右边 = | - | 3 | × | 18 | + | 3 | × | 2 | x | + | 6 | x |
| = | - | 54 | + | 6 | x | + | 6 | x |
| = | - | 54 | + | 12 | x |
| 68 | − | 110 | x | = | - | 54 | + | 12 | x |
| - | 110 | x | − | 12 | x | = | - | 54 | − | 68 |
| - | 122 | x | = | - | 54 | − | 68 |
| - | 122 | x | = | - | 122 |
| 122 | = | 122 | x |
| 122 | x | = | 122 |
| x | = | 122 | ÷ | 122 |
| = | 122 | × | 1 122 |
| = | 1 | × | 1 |
| x | = | 1 |
