| 2 | x | ÷ | ( | 200000 | ( | 1 | + | x | ÷ | 200000 | ) | ) | = | 2 25 |
| Multiply both sides of the equation by: | ( | 200000 | ( | 1 | + | x | ÷ | 200000 | ) | ) |
| 2 | x | = | 2 25 | ( | 200000 | ( | 1 | + | x | ÷ | 200000 | ) | ) |
| 2 | x | = | 2 25 | × | 200000 | ( | 1 | + | x | ÷ | 200000 | ) |
| 2 | x | = | 16000 | ( | 1 | + | x | ÷ | 200000 | ) |
| 2 | x | = | 16000 | × | 1 | + | 16000 | x | ÷ | 200000 |
| 2 | x | = | 16000 | + | 2 25 | x |
| 2 | x | − | 2 25 | x | = | 16000 |
48 25 | x | = | 16000 |
| x | = | 16000 | ÷ | 48 25 |
| = | 16000 | × | 25 48 |
| = | 1000 | × | 25 3 |
| x | = | 25000 3 |
| x | = | 8333.333333 |
