| ( | 68 | − | x | ) | ÷ | 68 | = | 41 500 |
| Left side of the equation = | 68 | × | 1 68 | − | x | × | 1 68 |
| = | 1 | − | x | × | 1 68 |
| 1 | − | 1 68 | x | = | 41 500 |
| - | 1 68 | x | = | 41 500 | − | 1 |
| - | 1 68 | x | = | - | 459 500 |
459 500 | = | 1 68 | x |
1 68 | x | = | 459 500 |
| x | = | 459 500 | ÷ | 1 68 |
| = | 459 500 | × | 68 |
| = | 459 125 | × | 17 |
| x | = | 7803 125 |
| x | = | 62.424 |
