| x | ÷ | ( | x | + | 100000 | ) | = | 7 200 |
| Multiply both sides of the equation by: | ( | x | + | 100000 | ) |
| x | = | 7 200 | ( | x | + | 100000 | ) |
| x | = | 7 200 | x | + | 7 200 | × | 100000 |
| x | = | 7 200 | x | + | 3500 |
| x | − | 7 200 | x | = | 3500 |
193 200 | x | = | 3500 |
| x | = | 3500 | ÷ | 193 200 |
| = | 3500 | × | 200 193 |
| x | = | 700000 193 |
| x | = | 3626.943005 |
