| ( | 6 | x | − | 5 | ) | + | ( | 2 | x | − | ( | 4 | x | − | 1 | ) | ) | = | 24 |
| Left side of the equation = | 6 | x | − | 5 | + | ( | 2 | x | − | ( | 4 | x | − | 1 | ) | ) |
| = | 6 | x | − | 5 | + | 2 | x | − | ( | 4 | x | − | 1 | ) |
| = | 8 | x | − | 5 | − | ( | 4 | x | − | 1 | ) |
| = | 8 | x | − | 5 | − | 4 | x | + | 1 |
| = | 4 | x | − | 4 |
| 4 | x | − | 4 | = | 24 |
| 4 | x | = | 24 | + | 4 |
| 4 | x | = | 28 |
| x | = | 28 | ÷ | 4 |
| = | 28 | × | 1 4 |
| = | 7 | × | 1 |
| x | = | 7 |
