| 979 | − | 6 | ( | 6 | x | − | 1693 | ) | = | 2755 | − | 6 | ( | 10 | x | + | 125 | ) |
| 方程左边 = | 979 | − | 6 | × | 6 | x | + | 6 | × | 1693 |
| = | 979 | − | 36 | x | + | 10158 |
| = | 11137 | − | 36 | x |
| 11137 | − | 36 | x | = | 2755 | − | 6 | ( | 10 | x | + | 125 | ) |
| 方程右边 = | 2755 | − | 6 | × | 10 | x | − | 6 | × | 125 |
| = | 2755 | − | 60 | x | − | 750 |
| = | 2005 | − | 60 | x |
| 11137 | − | 36 | x | = | 2005 | − | 60 | x |
| - | 36 | x | + | 60 | x | = | 2005 | − | 11137 |
| 24 | x | = | 2005 | − | 11137 |
| 24 | x | = | - | 9132 |
| x | = | - | 9132 | ÷ | 24 |
| = | - | 9132 | × | 1 24 |
| = | - | 761 | × | 1 2 |
| x | = | - | 761 2 |
| x | = | - 380.5 |
