| ( | 10000 | H | − | 700000 | ) | ( | 1 | − | 5 100 | ) | = | 250000 |
| Left side of the equation = | 10000 | H | ( | 1 | − | 5 100 | ) | − | 700000 | ( | 1 | − | 5 100 | ) |
| = | 10000 | H | × | 1 | − | 10000 | H | × | 5 100 | − | 700000 | ( | 1 | − | 5 100 | ) |
| = | 10000 | H | − | 500 | H | − | 700000 | ( | 1 | − | 5 100 | ) |
| = | 9500 | H | − | 700000 | ( | 1 | − | 5 100 | ) |
| = | 9500 | H | − | 700000 | × | 1 | + | 700000 | × | 5 100 |
| = | 9500 | H | − | 700000 | + | 35000 |
| = | 9500 | H | − | 665000 |
| 9500 | H | − | 665000 | = | 250000 |
| 9500 | H | = | 250000 | + | 665000 |
| 9500 | H | = | 915000 |
| H | = | 915000 | ÷ | 9500 |
| = | 915000 | × | 1 9500 |
| = | 1830 | × | 1 19 |
| H | = | 1830 19 |
| H | = | 96.315789 |
