| ( | 921 50 | − | x | ) | ÷ | x | = | 87 250 |
| Multiply both sides of the equation by: | x |
| ( | 921 50 | − | x | ) | = | 87 250 | x |
921 50 | − | x | = | 87 250 | x |
| - | x | − | 87 250 | x | = | - | 921 50 |
| - | 337 250 | x | = | - | 921 50 |
921 50 | = | 337 250 | x |
337 250 | x | = | 921 50 |
| x | = | 921 50 | ÷ | 337 250 |
| = | 921 50 | × | 250 337 |
| = | 921 | × | 5 337 |
| x | = | 4605 337 |
| x | = | 13.664688 |
