| X | ÷ | ( | 100 | + | X | ) | × | 100 100 | = | 573 1000 |
| Multiply both sides of the equation by: | ( | 100 | + | X | ) |
| X | × | 100 100 | = | 573 1000 | ( | 100 | + | X | ) |
| X | × | 100 100 | = | 573 1000 | × | 100 | + | 573 1000 | X |
| X | × | 100 100 | = | 573 10 | + | 573 1000 | X |
100 100 | X | − | 573 1000 | X | = | 573 10 |
427 1000 | X | = | 573 10 |
| X | = | 573 10 | ÷ | 427 1000 |
| = | 573 10 | × | 1000 427 |
| = | 573 | × | 100 427 |
| X | = | 57300 427 |
| X | = | 134.192037 |
