| x | − | x | × | 1 25 | − | ( | x | − | x | × | 1 25 | ) | × | 1 100 | = | 11000 |
| Left side of the equation = | 24 25 | x | − | ( | x | − | x | × | 1 25 | ) | × | 1 100 |
24 25 | x | − | ( | x | − | x | × | 1 25 | ) | × | 1 100 | = | 11000 |
| Left side of the equation = | 24 25 | x | − | x | × | 1 100 | + | x | × | 1 25 | × | 1 100 |
| = | 24 25 | x | − | x | × | 1 100 | + | x | × | 1 2500 |
| = | 594 625 | x |
594 625 | x | = | 11000 |
| x | = | 11000 | ÷ | 594 625 |
| = | 11000 | × | 625 594 |
| = | 500 | × | 625 27 |
