| ( | 5510 | − | y | ) | ÷ | y | = | 9 500 |
| Multiply both sides of the equation by: | y |
| ( | 5510 | − | y | ) | = | 9 500 | y |
| 5510 | − | y | = | 9 500 | y |
| - | y | − | 9 500 | y | = | - | 5510 |
| - | 509 500 | y | = | - | 5510 |
| 5510 | = | 509 500 | y |
509 500 | y | = | 5510 |
| y | = | 5510 | ÷ | 509 500 |
| = | 5510 | × | 500 509 |
| y | = | 2755000 509 |
| y | = | 5412.573674 |
