| 3 | ( | 32 | + | v | ) | = | 4 | ( | 32 | + | v | ) | + | 10 |
| Left side of the equation = | 3 | × | 32 | + | 3 | v |
| = | 96 | + | 3 | v |
| 96 | + | 3 | v | = | 4 | ( | 32 | + | v | ) | + | 10 |
| Right side of the equation = | 4 | × | 32 | + | 4 | v | + | 10 |
| = | 128 | + | 4 | v | + | 10 |
| = | 138 | + | 4 | v |
| 96 | + | 3 | v | = | 138 | + | 4 | v |
| 3 | v | − | 4 | v | = | 138 | − | 96 |
| - | v | = | 138 | − | 96 |
| - | v | = | 138 | − | 96 |
| - | v | = | 42 |
| - | 42 | = | v |
| v | = | - | 42 |
