( | 2624 5 | − | y | ) | ÷ | y | = | 69 1000 |
方程两边同时乘以: | y |
( | 2624 5 | − | y | ) | = | 69 1000 | y |
2624 5 | − | y | = | 69 1000 | y |
- | y | − | 69 1000 | y | = | - | 2624 5 |
- | 1069 1000 | y | = | - | 2624 5 |
2624 5 | = | 1069 1000 | y |
1069 1000 | y | = | 2624 5 |
y | = | 2624 5 | ÷ | 1069 1000 |
= | 2624 5 | × | 1000 1069 |
= | 2624 | × | 200 1069 |
y | = | 524800 1069 |
