| X | ÷ | ( | 2873 10 | + | X | ) | = | 3 20 |
| Multiply both sides of the equation by: | ( | 2873 10 | + | X | ) |
| X | = | 3 20 | ( | 2873 10 | + | X | ) |
| X | = | 3 20 | × | 2873 10 | + | 3 20 | X |
| X | = | 8619 200 | + | 3 20 | X |
| X | − | 3 20 | X | = | 8619 200 |
17 20 | X | = | 8619 200 |
| X | = | 8619 200 | ÷ | 17 20 |
| = | 8619 200 | × | 20 17 |
| = | 507 10 | × | 1 |
| X | = | 507 10 |
| X | = | 50.7 |
