| 6 | x | − | 38 | ( | x | + | 26 | ) | = | 26 | x | − | 2380 |
| 方程左边 = | 6 | x | − | 38 | x | − | 38 | × | 26 |
| = | 6 | x | − | 38 | x | − | 988 |
| = | - | 32 | x | − | 988 |
| - | 32 | x | − | 988 | = | 26 | x | − | 2380 |
| - | 32 | x | − | 26 | x | = | - | 2380 | + | 988 |
| - | 58 | x | = | - | 2380 | + | 988 |
| - | 58 | x | = | - | 1392 |
| 1392 | = | 58 | x |
| 58 | x | = | 1392 |
| x | = | 1392 | ÷ | 58 |
| = | 1392 | × | 1 58 |
| = | 24 | × | 1 |
| x | = | 24 |
