1 50 | = | Y | × | 3333 10000 | + | ( | 1 | − | Y | ) | ( | - | 1 4 | ) |
| 方程右边 = | 3333 10000 | Y | + | 1 | ( | - | 1 4 | ) | − | Y | ( | - | 1 4 | ) |
| = | 3333 10000 | Y | − | 1 | × | 1 4 | − | Y | ( | - | 1 4 | ) |
| = | 3333 10000 | Y | − | 1 4 | − | Y | ( | - | 1 4 | ) |
| = | 3333 10000 | Y | − | 1 4 | + | Y | × | 1 4 |
| = | 5833 10000 | Y | − | 1 4 |
1 50 | = | 5833 10000 | Y | − | 1 4 |
| - | 5833 10000 | Y | = | - | 1 4 | − | 1 50 |
| - | 5833 10000 | Y | = | - | 27 100 |
27 100 | = | 5833 10000 | Y |
5833 10000 | Y | = | 27 100 |
| Y | = | 27 100 | ÷ | 5833 10000 |
| = | 27 100 | × | 10000 5833 |
| = | 27 | × | 100 5833 |
| Y | = | 2700 5833 |
| Y | = | 0.462884 |
