| 979 | − | 6 | ( | 6 | x | − | 163 | ) | = | 2755 | − | 6 | ( | 10 | x | + | 125 | ) |
| Left side of the equation = | 979 | − | 6 | × | 6 | x | + | 6 | × | 163 |
| = | 979 | − | 36 | x | + | 978 |
| = | 1957 | − | 36 | x |
| 1957 | − | 36 | x | = | 2755 | − | 6 | ( | 10 | x | + | 125 | ) |
| Right side of the equation = | 2755 | − | 6 | × | 10 | x | − | 6 | × | 125 |
| = | 2755 | − | 60 | x | − | 750 |
| = | 2005 | − | 60 | x |
| 1957 | − | 36 | x | = | 2005 | − | 60 | x |
| - | 36 | x | + | 60 | x | = | 2005 | − | 1957 |
| 24 | x | = | 2005 | − | 1957 |
| 24 | x | = | 48 |
| x | = | 48 | ÷ | 24 |
| = | 48 | × | 1 24 |
| = | 2 | × | 1 |
| x | = | 2 |
