| 2 | = | 100 | ( | x | − | 216 | ) | ÷ | ( | x | × | 1200 | ÷ | 100 | ) |
| Multiply both sides of the equation by: | ( | x | × | 1200 | ÷ | 100 | ) |
| 2 | ( | x | × | 1200 | ÷ | 100 | ) | = | 100 | ( | x | − | 216 | ) |
| 2 | x | × | 1200 | ÷ | 100 | = | 100 | ( | x | − | 216 | ) |
| 2 | x | × | 1200 | ÷ | 100 | = | 100 | x | − | 100 | × | 216 |
| 24 | x | = | 100 | x | − | 21600 |
| 24 | x | − | 100 | x | = | - | 21600 |
| - | 76 | x | = | - | 21600 |
| 21600 | = | 76 | x |
| 76 | x | = | 21600 |
| x | = | 21600 | ÷ | 76 |
| = | 21600 | × | 1 76 |
| = | 5400 | × | 1 19 |
| x | = | 5400 19 |
| x | = | 284.210526 |
