| ( | 5500 | − | x | ) | ÷ | ( | 8250 | + | x | ) | = | 3 2 |
| Multiply both sides of the equation by: | ( | 8250 | + | x | ) |
| ( | 5500 | − | x | ) | = | 3 2 | ( | 8250 | + | x | ) |
| 5500 | − | x | = | 3 2 | ( | 8250 | + | x | ) |
| 5500 | − | x | = | 3 2 | × | 8250 | + | 3 2 | x |
| 5500 | − | x | = | 12375 | + | 3 2 | x |
| - | x | − | 3 2 | x | = | 12375 | − | 5500 |
| - | 5 2 | x | = | 12375 | − | 5500 |
| - | 5 2 | x | = | 6875 |
| - | 6875 | = | 5 2 | x |
5 2 | x | = | - | 6875 |
| x | = | - | 6875 | ÷ | 5 2 |
| = | - | 6875 | × | 2 5 |
| = | - | 1375 | × | 2 |
| x | = | - | 2750 |
