( | 2911 5 | − | y | ) | ÷ | y | = | 71 1000 |
方程两边同时乘以: | y |
( | 2911 5 | − | y | ) | = | 71 1000 | y |
2911 5 | − | y | = | 71 1000 | y |
- | y | − | 71 1000 | y | = | - | 2911 5 |
- | 1071 1000 | y | = | - | 2911 5 |
2911 5 | = | 1071 1000 | y |
1071 1000 | y | = | 2911 5 |
y | = | 2911 5 | ÷ | 1071 1000 |
= | 2911 5 | × | 1000 1071 |
= | 2911 | × | 200 1071 |
y | = | 582200 1071 |
