| 2 | x | ÷ | ( | 3 20 | − | x | ) | × | ( | 3 20 | − | x | ) | = | 523 10 |
| Multiply both sides of the equation by: | ( | 3 20 | − | x | ) |
| 2 | x | ( | 3 20 | − | x | ) | = | 523 10 | ( | 3 20 | − | x | ) |
| 2 | x | × | 3 20 | − | 2 | x | x | = | 523 10 | ( | 3 20 | − | x | ) |
| 2 | x | × | 3 20 | − | 2 | x | x | = | 523 10 | × | 3 20 | − | 523 10 | x |
3 10 | x | − | 2 | x | x | = | 1569 200 | − | 523 10 | x |
| x= | 523 20 |
