| 5 | ( | x | − | 1 | ) | − | 3 | = | 4 | ( | x | − | 1 | ) | + | 3 |
| Left side of the equation = | 5 | x | − | 5 | × | 1 | − | 3 |
| = | 5 | x | − | 5 | − | 3 |
| = | 5 | x | − | 8 |
| 5 | x | − | 8 | = | 4 | ( | x | − | 1 | ) | + | 3 |
| Right side of the equation = | 4 | x | − | 4 | × | 1 | + | 3 |
| = | 4 | x | − | 4 | + | 3 |
| = | 4 | x | − | 1 |
| 5 | x | − | 8 | = | 4 | x | − | 1 |
| 5 | x | − | 4 | x | = | - | 1 | + | 8 |
| x | = | - | 1 | + | 8 |
