( | 20077 10 | − | y | ) | ÷ | y | = | 27 1000 |
方程两边同时乘以: | y |
( | 20077 10 | − | y | ) | = | 27 1000 | y |
20077 10 | − | y | = | 27 1000 | y |
- | y | − | 27 1000 | y | = | - | 20077 10 |
- | 1027 1000 | y | = | - | 20077 10 |
20077 10 | = | 1027 1000 | y |
1027 1000 | y | = | 20077 10 |
y | = | 20077 10 | ÷ | 1027 1000 |
= | 20077 10 | × | 1000 1027 |
= | 20077 | × | 100 1027 |
y | = | 2007700 1027 |
