| 4 | × | 1 | ( | 6 | + | 6 | ) | + | m | × | 1 | × | 6 | = | 12 | × | 5 | + | 48 |
| Left side of the equation = | 4 | ( | 6 | + | 6 | ) | + | m | × | 6 |
| 4 | ( | 6 | + | 6 | ) | + | 6 | m | = | 12 | × | 5 | + | 48 |
| Left side of the equation = | 4 | × | 6 | + | 4 | × | 6 | + | 6 | m |
| = | 24 | + | 24 | + | 6 | m |
| = | 48 | + | 6 | m |
| 48 | + | 6 | m | = | 12 | × | 5 | + | 48 |
| Right side of the equation = | 60 | + | 48 |
| = | 108 |
| 48 | + | 6 | m | = | 108 |
| 6 | m | = | 108 | − | 48 |
| 6 | m | = | 60 |
| m | = | 60 | ÷ | 6 |
| = | 60 | × | 1 6 |
| = | 10 | × | 1 |
| m | = | 10 |
