| 5 | + | ( | x | × | 21 20 | + | 5 | ) | + | 3 20 | x | + | ( | 1 10 | x | × | 331 2000 | ) | = | 10286 25 |
| Left side of the equation = | 5 | + | x | × | 21 20 | + | 5 | + | 3 20 | x | + | ( | 1 10 | x | × | 331 2000 | ) |
| = | 10 | + | 6 5 | x | + | ( | 1 10 | x | × | 331 2000 | ) |
| = | 10 | + | 6 5 | x | + | 1 10 | x | × | 331 2000 |
| = | 10 | + | 6 5 | x | + | 331 20000 | x |
| = | 10 | + | 24331 20000 | x |
| 10 | + | 24331 20000 | x | = | 10286 25 |
24331 20000 | x | = | 10286 25 | − | 10 |
24331 20000 | x | = | 10036 25 |
| x | = | 10036 25 | ÷ | 24331 20000 |
