| ( | 582 | − | x | ) | ÷ | ( | x | − | 571 | ) | = | - | 115 | ÷ | 63 |
| Multiply both sides of the equation by: | ( | x | − | 571 | ) |
| ( | 582 | − | x | ) | = | - | 115 | ÷ | 63 | × | ( | x | − | 571 | ) |
| 582 | − | x | = | - | 115 | ÷ | 63 | × | ( | x | − | 571 | ) |
| 582 | − | x | = | - | 115 | ÷ | 63 | × | x | + | 115 | ÷ | 63 | × | 571 |
| 582 | − | x | = | - | 115 63 | x | + | 65665 63 |
| - | x | + | 115 63 | x | = | 65665 63 | − | 582 |
52 63 | x | = | 65665 63 | − | 582 |
52 63 | x | = | 28999 63 |
| x | = | 28999 63 | ÷ | 52 63 |
| = | 28999 63 | × | 63 52 |
| = | 28999 | × | 1 52 |
| x | = | 28999 52 |
| x | = | 557.673077 |
