| x | ÷ | ( | 1 | − | x | ) | ÷ | 18 | = | 27 250 |
| Multiply both sides of the equation by: | ( | 1 | − | x | ) |
| x | ÷ | 18 | = | 27 250 | ( | 1 | − | x | ) |
| x | ÷ | 18 | = | 27 250 | × | 1 | − | 27 250 | x |
| x | × | 1 18 | = | 27 250 | − | 27 250 | x |
1 18 | x | + | 27 250 | x | = | 27 250 |
184 1125 | x | = | 27 250 |
| x | = | 27 250 | ÷ | 184 1125 |
| = | 27 250 | × | 1125 184 |
| = | 27 2 | × | 9 184 |
| x | = | 243 368 |
| x | = | 0.660326 |
