3 100 | = | X | ÷ | ( | X | + | 266 | ) |
| Multiply both sides of the equation by: | ( | X | + | 266 | ) |
3 100 | ( | X | + | 266 | ) | = | X |
3 100 | X | + | 3 100 | × | 266 | = | X |
3 100 | X | + | 399 50 | = | X |
3 100 | X | − | X | = | - | 399 50 |
| - | 97 100 | X | = | - | 399 50 |
399 50 | = | 97 100 | X |
97 100 | X | = | 399 50 |
| X | = | 399 50 | ÷ | 97 100 |
| = | 399 50 | × | 100 97 |
| = | 399 | × | 2 97 |
| X | = | 798 97 |
| X | = | 8.226804 |
