23 25 | = | X | ÷ | ( | X | + | 10 | ) |
| Multiply both sides of the equation by: | ( | X | + | 10 | ) |
23 25 | ( | X | + | 10 | ) | = | X |
23 25 | X | + | 23 25 | × | 10 | = | X |
23 25 | X | + | 46 5 | = | X |
23 25 | X | − | X | = | - | 46 5 |
| - | 2 25 | X | = | - | 46 5 |
46 5 | = | 2 25 | X |
2 25 | X | = | 46 5 |
| X | = | 46 5 | ÷ | 2 25 |
| = | 46 5 | × | 25 2 |
| = | 23 | × | 5 |
| X | = | 115 |
