| ( | 4046 | − | X | ) | ÷ | X | = | 187 5000 |
| Multiply both sides of the equation by: | X |
| ( | 4046 | − | X | ) | = | 187 5000 | X |
| 4046 | − | X | = | 187 5000 | X |
| - | X | − | 187 5000 | X | = | - | 4046 |
| - | 5187 5000 | X | = | - | 4046 |
| 4046 | = | 5187 5000 | X |
5187 5000 | X | = | 4046 |
| X | = | 4046 | ÷ | 5187 5000 |
| = | 4046 | × | 5000 5187 |
| = | 578 | × | 5000 741 |
| X | = | 2890000 741 |
| X | = | 3900.134953 |
