| ( | 9883 2000 | − | y | ) | ÷ | y | = | 3891 2500 |
| Multiply both sides of the equation by: | y |
| ( | 9883 2000 | − | y | ) | = | 3891 2500 | y |
9883 2000 | − | y | = | 3891 2500 | y |
| - | y | − | 3891 2500 | y | = | - | 9883 2000 |
| - | 6391 2500 | y | = | - | 9883 2000 |
9883 2000 | = | 6391 2500 | y |
6391 2500 | y | = | 9883 2000 |
| y | = | 9883 2000 | ÷ | 6391 2500 |
| = | 9883 2000 | × | 2500 6391 |
| = | 9883 4 | × | 5 6391 |
| y | = | 49415 25564 |
