( | 26612 5 | − | y | ) | ÷ | y | = | 12 500 |
方程两边同时乘以: | y |
( | 26612 5 | − | y | ) | = | 12 500 | y |
26612 5 | − | y | = | 12 500 | y |
- | y | − | 12 500 | y | = | - | 26612 5 |
- | 128 125 | y | = | - | 26612 5 |
26612 5 | = | 128 125 | y |
128 125 | y | = | 26612 5 |
y | = | 26612 5 | ÷ | 128 125 |
= | 26612 5 | × | 125 128 |
= | 6653 | × | 25 32 |
