( | 25273 10 | − | y | ) | ÷ | y | = | 3 100 |
方程两边同时乘以: | y |
( | 25273 10 | − | y | ) | = | 3 100 | y |
25273 10 | − | y | = | 3 100 | y |
- | y | − | 3 100 | y | = | - | 25273 10 |
- | 103 100 | y | = | - | 25273 10 |
25273 10 | = | 103 100 | y |
103 100 | y | = | 25273 10 |
y | = | 25273 10 | ÷ | 103 100 |
= | 25273 10 | × | 100 103 |
= | 25273 | × | 10 103 |
y | = | 252730 103 |
y | = | 2453.68932 |
