5 100 | = | ( | X | − | 1801 | ) | ÷ | 1801 |
| Right side of the equation = | X | × | 1 1801 | − | 1801 | × | 1 1801 |
| = | X | × | 1 1801 | − | 1801 1801 |
5 100 | = | 1 1801 | X | − | 1801 1801 |
| - | 1 1801 | X | = | - | 1801 1801 | − | 5 100 |
| - | 1 1801 | X | = | - | 37821 36020 |
37821 36020 | = | 1 1801 | X |
1 1801 | X | = | 37821 36020 |
| X | = | 37821 36020 | ÷ | 1 1801 |
| = | 37821 36020 | × | 1801 |
