| 600 | x | ÷ | ( | 1800 | ( | 1 | − | x | ) | ) | = | 3 50 |
| Multiply both sides of the equation by: | ( | 1800 | ( | 1 | − | x | ) | ) |
| 600 | x | = | 3 50 | ( | 1800 | ( | 1 | − | x | ) | ) |
| 600 | x | = | 3 50 | × | 1800 | ( | 1 | − | x | ) |
| 600 | x | = | 108 | ( | 1 | − | x | ) |
| 600 | x | = | 108 | × | 1 | − | 108 | x |
| 600 | x | = | 108 | − | 108 | x |
| 600 | x | + | 108 | x | = | 108 |
| 708 | x | = | 108 |
| x | = | 108 | ÷ | 708 |
| = | 108 | × | 1 708 |
| = | 9 | × | 1 59 |
| x | = | 9 59 |
| x | = | 0.152542 |
