| 5 | ÷ | 2 | = | ( | - | 1 | ÷ | 4 | ) | ( | 9 | ÷ | 4 | ) | + | h |
| Left side of the equation = | 5 2 |
5 2 | = | ( | - | 1 | ÷ | 4 | ) | ( | 9 | ÷ | 4 | ) | + | h |
| Right side of the equation = | - | 1 | ÷ | 4 | × | ( | 9 | ÷ | 4 | ) | + | h |
| = | - | 1 4 | ( | 9 | ÷ | 4 | ) | + | h |
| = | - | 1 4 | × | 9 | ÷ | 4 | + | h |
| = | - | 9 16 | + | h |
5 2 | = | - | 9 16 | + | h |
| - | h | = | - | 9 16 | − | 5 2 |
| - | h | = | - | 49 16 |
49 16 | = | h |
| h | = | 49 16 |
