84 5 | x | + | 17 2 | ( | 1000 | − | x | ) | = | 0 |
| Left side of the equation = | 84 5 | x | + | 17 2 | × | 1000 | − | 17 2 | x |
| = | 84 5 | x | + | 8500 | − | 17 2 | x |
| = | 83 10 | x | + | 8500 |
83 10 | x | + | 8500 | = | 0 |
83 10 | x | = | 0 | − | 8500 |
83 10 | x | = | - | 8500 |
| x | = | - | 8500 | ÷ | 83 10 |
| = | - | 8500 | × | 10 83 |
| x | = | - | 85000 83 |
| x | = | - 1024.096386 |
