| 25 | = | 1 | ( | 1 | + | x | ) | ÷ | 43 500 | − | x |
| Right side of the equation = | 500 43 | ( | 1 | + | x | ) | − | x |
| 25 | = | 500 43 | ( | 1 | + | x | ) | − | x |
| Right side of the equation = | 500 43 | × | 1 | + | 500 43 | x | − | x |
| = | 500 43 | + | 500 43 | x | − | x |
| = | 500 43 | + | 457 43 | x |
| 25 | = | 500 43 | + | 457 43 | x |
| - | 457 43 | x | = | 500 43 | − | 25 |
| - | 457 43 | x | = | - | 575 43 |
575 43 | = | 457 43 | x |
457 43 | x | = | 575 43 |
| x | = | 575 43 | ÷ | 457 43 |
| = | 575 43 | × | 43 457 |
| = | 575 | × | 1 457 |
| x | = | 575 457 |
| x | = | 1.258206 |
