| x | = | 50 | − | ( | ( | 50 | + | ( | 50 | × | 20 100 | ) | ) | × | 10 100 | ) |
| Right side of the equation = | 50 | − | ( | 50 | + | ( | 50 | × | 20 100 | ) | ) | × | 10 100 |
| = | 50 | − | 50 | × | 10 100 | − | ( | 50 | × | 20 100 | ) | × | 10 100 |
| = | 50 | − | 5 | − | ( | 50 | × | 20 100 | ) | × | 10 100 |
| = | 45 | − | ( | 50 | × | 20 100 | ) | × | 10 100 |
| = | 45 | − | 50 | × | 20 100 | × | 10 100 |
| = | 45 | − | 1 |
| = | 44 |
