| ( | 8 | ( | 1 | + | 20 100 | ) | ) | + | ( | 3 100 | x | ) | = | x |
| Left side of the equation = | 8 | ( | 1 | + | 20 100 | ) | + | ( | 3 100 | x | ) |
| = | 8 | × | 1 | + | 8 | × | 20 100 | + | ( | 3 100 | x | ) |
| = | 8 | + | 8 5 | + | ( | 3 100 | x | ) |
| = | 48 5 | + | ( | 3 100 | x | ) |
| = | 48 5 | + | 3 100 | x |
48 5 | + | 3 100 | x | = | x |
3 100 | x | − | x | = | - | 48 5 |
| - | 97 100 | x | = | - | 48 5 |
48 5 | = | 97 100 | x |
97 100 | x | = | 48 5 |
| x | = | 48 5 | ÷ | 97 100 |
| = | 48 5 | × | 100 97 |
| = | 48 | × | 20 97 |
| x | = | 960 97 |
| x | = | 9.896907 |
