| 4 | ( | 6 | x | + | 8 | ) | + | 12 | = | 4 | ( | 6 | x | + | 8 | ) |
| Left side of the equation = | 4 | × | 6 | x | + | 4 | × | 8 | + | 12 |
| = | 24 | x | + | 32 | + | 12 |
| = | 24 | x | + | 44 |
| 24 | x | + | 44 | = | 4 | ( | 6 | x | + | 8 | ) |
| Right side of the equation = | 4 | × | 6 | x | + | 4 | × | 8 |
| = | 24 | x | + | 32 |
| 24 | x | + | 44 | = | 24 | x | + | 32 |
| 24 | x | − | 24 | x | = | 32 | − | 44 |
| 0 | x | = | 32 | − | 44 |
| 0 | x | = | - | 12 |
