( | 5441 10 | − | y | ) | ÷ | y | = | 69 1000 |
方程两边同时乘以: | y |
( | 5441 10 | − | y | ) | = | 69 1000 | y |
5441 10 | − | y | = | 69 1000 | y |
- | y | − | 69 1000 | y | = | - | 5441 10 |
- | 1069 1000 | y | = | - | 5441 10 |
5441 10 | = | 1069 1000 | y |
1069 1000 | y | = | 5441 10 |
y | = | 5441 10 | ÷ | 1069 1000 |
= | 5441 10 | × | 1000 1069 |
= | 5441 | × | 100 1069 |
y | = | 544100 1069 |
