( | 5217 10 | − | y | ) | ÷ | y | = | 7 100 |
方程两边同时乘以: | y |
( | 5217 10 | − | y | ) | = | 7 100 | y |
5217 10 | − | y | = | 7 100 | y |
- | y | − | 7 100 | y | = | - | 5217 10 |
- | 107 100 | y | = | - | 5217 10 |
5217 10 | = | 107 100 | y |
107 100 | y | = | 5217 10 |
y | = | 5217 10 | ÷ | 107 100 |
= | 5217 10 | × | 100 107 |
= | 5217 | × | 10 107 |
y | = | 52170 107 |
y | = | 487.570093 |
