| 10000 | = | 17 2 | x | + | 84 5 | ( | 1000 | − | x | ) |
| Right side of the equation = | 17 2 | x | + | 84 5 | × | 1000 | − | 84 5 | x |
| = | 17 2 | x | + | 16800 | − | 84 5 | x |
| = | - | 83 10 | x | + | 16800 |
| 10000 | = | - | 83 10 | x | + | 16800 |
83 10 | x | = | 16800 | − | 10000 |
83 10 | x | = | 6800 |
| x | = | 6800 | ÷ | 83 10 |
| = | 6800 | × | 10 83 |
| x | = | 68000 83 |
| x | = | 819.277108 |
