( | 2643 5 | − | y | ) | ÷ | y | = | 37 500 |
方程两边同时乘以: | y |
( | 2643 5 | − | y | ) | = | 37 500 | y |
2643 5 | − | y | = | 37 500 | y |
- | y | − | 37 500 | y | = | - | 2643 5 |
- | 537 500 | y | = | - | 2643 5 |
2643 5 | = | 537 500 | y |
537 500 | y | = | 2643 5 |
y | = | 2643 5 | ÷ | 537 500 |
= | 2643 5 | × | 500 537 |
= | 881 | × | 100 179 |
y | = | 88100 179 |
y | = | 492.178771 |
