| ( | ( | X | − | 82000 | ) | × | 1 20 | ) | + | X | = | 4836106 |
| Left side of the equation = | ( | X | − | 82000 | ) | × | 1 20 | + | X |
| = | X | × | 1 20 | − | 82000 | × | 1 20 | + | X |
| = | X | × | 1 20 | − | 4100 | + | X |
| = | 21 20 | X | − | 4100 |
21 20 | X | − | 4100 | = | 4836106 |
21 20 | X | = | 4836106 | + | 4100 |
21 20 | X | = | 4840206 |
| X | = | 4840206 | ÷ | 21 20 |
| = | 4840206 | × | 20 21 |
| = | 230486 | × | 20 |
| X | = | 4609720 |
