| 10 | = | 100 | ( | x | − | 203 | ) | ÷ | ( | x | × | 330 | ÷ | 100 | ) |
| Multiply both sides of the equation by: | ( | x | × | 330 | ÷ | 100 | ) |
| 10 | ( | x | × | 330 | ÷ | 100 | ) | = | 100 | ( | x | − | 203 | ) |
| 10 | x | × | 330 | ÷ | 100 | = | 100 | ( | x | − | 203 | ) |
| 10 | x | × | 330 | ÷ | 100 | = | 100 | x | − | 100 | × | 203 |
| 33 | x | = | 100 | x | − | 20300 |
| 33 | x | − | 100 | x | = | - | 20300 |
| - | 67 | x | = | - | 20300 |
| 20300 | = | 67 | x |
| 67 | x | = | 20300 |
| x | = | 20300 | ÷ | 67 |
| = | 20300 | × | 1 67 |
| x | = | 20300 67 |
| x | = | 302.985075 |
