( | 1177 2 | − | y | ) | ÷ | y | = | 73 1000 |
方程两边同时乘以: | y |
( | 1177 2 | − | y | ) | = | 73 1000 | y |
1177 2 | − | y | = | 73 1000 | y |
- | y | − | 73 1000 | y | = | - | 1177 2 |
- | 1073 1000 | y | = | - | 1177 2 |
1177 2 | = | 1073 1000 | y |
1073 1000 | y | = | 1177 2 |
y | = | 1177 2 | ÷ | 1073 1000 |
= | 1177 2 | × | 1000 1073 |
= | 1177 | × | 500 1073 |
y | = | 588500 1073 |
y | = | 548.462255 |
