| 8 | + | ( | x | × | 51 50 | + | 5 2 | ) | + | 3 20 | x | + | ( | 8 | × | 331 2000 | ) | = | 4931 100 |
| Left side of the equation = | 8 | + | x | × | 51 50 | + | 5 2 | + | 3 20 | x | + | ( | 8 | × | 331 2000 | ) |
| = | 21 2 | + | 117 100 | x | + | ( | 8 | × | 331 2000 | ) |
| = | 21 2 | + | 117 100 | x | + | 8 | × | 331 2000 |
| = | 21 2 | + | 117 100 | x | + | 331 250 |
| = | 1478 125 | + | 117 100 | x |
1478 125 | + | 117 100 | x | = | 4931 100 |
117 100 | x | = | 4931 100 | − | 1478 125 |
117 100 | x | = | 18743 500 |
| x | = | 18743 500 | ÷ | 117 100 |
| = | 18743 500 | × | 100 117 |
| = | 18743 5 | × | 1 117 |
| x | = | 18743 585 |
| x | = | 32.039316 |
