| ( | 5403 10 | − | y | ) | ÷ | y | = | 32 500 |
| Multiply both sides of the equation by: | y |
| ( | 5403 10 | − | y | ) | = | 32 500 | y |
5403 10 | − | y | = | 32 500 | y |
| - | y | − | 32 500 | y | = | - | 5403 10 |
| - | 133 125 | y | = | - | 5403 10 |
5403 10 | = | 133 125 | y |
133 125 | y | = | 5403 10 |
| y | = | 5403 10 | ÷ | 133 125 |
| = | 5403 10 | × | 125 133 |
| = | 5403 2 | × | 25 133 |
| y | = | 135075 266 |
| y | = | 507.800752 |
