| x | ÷ | ( | 150 | − | x | ) | = | 51 100 |
| Multiply both sides of the equation by: | ( | 150 | − | x | ) |
| x | = | 51 100 | ( | 150 | − | x | ) |
| x | = | 51 100 | × | 150 | − | 51 100 | x |
| x | = | 153 2 | − | 51 100 | x |
| x | + | 51 100 | x | = | 153 2 |
151 100 | x | = | 153 2 |
| x | = | 153 2 | ÷ | 151 100 |
| = | 153 2 | × | 100 151 |
| = | 153 | × | 50 151 |
| x | = | 7650 151 |
| x | = | 50.662252 |
