( | 4831 2 | − | y | ) | ÷ | y | = | 3 100 |
方程两边同时乘以: | y |
( | 4831 2 | − | y | ) | = | 3 100 | y |
4831 2 | − | y | = | 3 100 | y |
- | y | − | 3 100 | y | = | - | 4831 2 |
- | 103 100 | y | = | - | 4831 2 |
4831 2 | = | 103 100 | y |
103 100 | y | = | 4831 2 |
y | = | 4831 2 | ÷ | 103 100 |
= | 4831 2 | × | 100 103 |
= | 4831 | × | 50 103 |
y | = | 241550 103 |
y | = | 2345.145631 |
