| 24 | − | 1 | ÷ | 2 | = | 3 | + | 9 | ÷ | 2 | + | 2 | m |
| Left side of the equation = | 24 | − | 1 2 |
| = | 47 2 |
47 2 | = | 3 | + | 9 | ÷ | 2 | + | 2 | m |
| Right side of the equation = | 3 | + | 9 2 | + | 2 | m |
| = | 15 2 | + | 2 | m |
47 2 | = | 15 2 | + | 2 | m |
| - | 2 | m | = | 15 2 | − | 47 2 |
| - | 2 | m | = | - | 16 |
| 16 | = | 2 | m |
| 2 | m | = | 16 |
| m | = | 16 | ÷ | 2 |
| = | 16 | × | 1 2 |
| = | 8 | × | 1 |
| m | = | 8 |
