| X | ÷ | ( | X | − | 473 50 | ) | = | 21 5 |
| Multiply both sides of the equation by: | ( | X | − | 473 50 | ) |
| X | = | 21 5 | ( | X | − | 473 50 | ) |
| X | = | 21 5 | X | − | 21 5 | × | 473 50 |
| X | = | 21 5 | X | − | 9933 250 |
| X | − | 21 5 | X | = | - | 9933 250 |
| - | 16 5 | X | = | - | 9933 250 |
9933 250 | = | 16 5 | X |
16 5 | X | = | 9933 250 |
| X | = | 9933 250 | ÷ | 16 5 |
| = | 9933 250 | × | 5 16 |
| = | 9933 50 | × | 1 16 |
| X | = | 9933 800 |
| X | = | 12.41625 |
