1 10 | x | + | ( | x | × | 21 20 | + | 50 | + | 3 20 | x | + | ( | 1 10 | x | × | 331 2000 | ) | ) | = | 8447 100 |
| Left side of the equation = | 1 10 | x | + | x | × | 21 20 | + | 50 | + | 3 20 | x | + | ( | 1 10 | x | × | 331 2000 | ) |
| = | 13 10 | x | + | 50 | + | ( | 1 10 | x | × | 331 2000 | ) |
| = | 13 10 | x | + | 50 | + | 1 10 | x | × | 331 2000 |
| = | 13 10 | x | + | 50 | + | 331 20000 | x |
| = | 26331 20000 | x | + | 50 |
26331 20000 | x | + | 50 | = | 8447 100 |
26331 20000 | x | = | 8447 100 | − | 50 |
26331 20000 | x | = | 3447 100 |
| x | = | 3447 100 | ÷ | 26331 20000 |
| = | 3447 100 | × | 20000 26331 |
| = | 1149 | × | 200 8777 |
| x | = | 229800 8777 |
