( | 2771 5 | − | y | ) | ÷ | y | = | 38 500 |
方程两边同时乘以: | y |
( | 2771 5 | − | y | ) | = | 38 500 | y |
2771 5 | − | y | = | 38 500 | y |
- | y | − | 38 500 | y | = | - | 2771 5 |
- | 269 250 | y | = | - | 2771 5 |
2771 5 | = | 269 250 | y |
269 250 | y | = | 2771 5 |
y | = | 2771 5 | ÷ | 269 250 |
= | 2771 5 | × | 250 269 |
= | 2771 | × | 50 269 |
y | = | 138550 269 |
y | = | 515.055762 |
