| ( | 20601 10 | − | y | ) | ÷ | y | = | 3 100 |
| Multiply both sides of the equation by: | y |
| ( | 20601 10 | − | y | ) | = | 3 100 | y |
20601 10 | − | y | = | 3 100 | y |
| - | y | − | 3 100 | y | = | - | 20601 10 |
| - | 103 100 | y | = | - | 20601 10 |
20601 10 | = | 103 100 | y |
103 100 | y | = | 20601 10 |
| y | = | 20601 10 | ÷ | 103 100 |
| = | 20601 10 | × | 100 103 |
| = | 20601 | × | 10 103 |
| y | = | 206010 103 |
| y | = | 2000.097087 |
