| 4 | m | − | 8 | − | 8 | = | 3 | m | − | 6 | + | 3 | m |
| Left side of the equation = | 4 | m | − | 16 |
| 4 | m | − | 16 | = | 3 | m | − | 6 | + | 3 | m |
| Right side of the equation = | 6 | m | − | 6 |
| 4 | m | − | 16 | = | 6 | m | − | 6 |
| 4 | m | − | 6 | m | = | - | 6 | + | 16 |
| - | 2 | m | = | - | 6 | + | 16 |
| - | 2 | m | = | 10 |
| - | 10 | = | 2 | m |
| 2 | m | = | - | 10 |
| m | = | - | 10 | ÷ | 2 |
| = | - | 10 | × | 1 2 |
| = | - | 5 | × | 1 |
| m | = | - | 5 |
