| ( | 82 | ( | 1 | + | 20 100 | ) | ) | + | ( | 6 100 | x | ) | = | x |
| Left side of the equation = | 82 | ( | 1 | + | 20 100 | ) | + | ( | 6 100 | x | ) |
| = | 82 | × | 1 | + | 82 | × | 20 100 | + | ( | 6 100 | x | ) |
| = | 82 | + | 82 5 | + | ( | 6 100 | x | ) |
| = | 492 5 | + | ( | 6 100 | x | ) |
| = | 492 5 | + | 6 100 | x |
492 5 | + | 6 100 | x | = | x |
6 100 | x | − | x | = | - | 492 5 |
| - | 47 50 | x | = | - | 492 5 |
492 5 | = | 47 50 | x |
47 50 | x | = | 492 5 |
| x | = | 492 5 | ÷ | 47 50 |
| = | 492 5 | × | 50 47 |
| = | 492 | × | 10 47 |
| x | = | 4920 47 |
| x | = | 104.680851 |
