| 3 | ( | 2 | x | − | 1 | ) | + | 1 | = | x | − | 5 | ( | 2 | x | − | 1 | ) |
| Left side of the equation = | 3 | × | 2 | x | − | 3 | × | 1 | + | 1 |
| = | 6 | x | − | 3 | + | 1 |
| = | 6 | x | − | 2 |
| 6 | x | − | 2 | = | x | − | 5 | ( | 2 | x | − | 1 | ) |
| Right side of the equation = | x | − | 5 | × | 2 | x | + | 5 | × | 1 |
| = | x | − | 10 | x | + | 5 |
| = | - | 9 | x | + | 5 |
| 6 | x | − | 2 | = | - | 9 | x | + | 5 |
| 6 | x | + | 9 | x | = | 5 | + | 2 |
| 15 | x | = | 5 | + | 2 |
| 15 | x | = | 7 |
| x | = | 7 | ÷ | 15 |
| = | 7 | × | 1 15 |
| x | = | 7 15 |
| x | = | 0.466667 |
