| 方程左边 = | 3 2 | + | 3 2 | − | 2 | h |
| = | 3 | − | 2 | h |
| 3 | − | 2 | h | = | 349393 500000 |
| - | 2 | h | = | 349393 500000 | − | 3 |
| - | 2 | h | = | - | 1150607 500000 |
1150607 500000 | = | 2 | h |
| 2 | h | = | 1150607 500000 |
| h | = | 1150607 500000 | ÷ | 2 |
| = | 1150607 500000 | × | 1 2 |
| h | = | 1150607 1000000 |
