| X | = | 1 20 | ( | X | + | 20057 25 | ) |
| Right side of the equation = | 1 20 | X | + | 1 20 | × | 20057 25 |
| = | 1 20 | X | + | 20057 500 |
| X | = | 1 20 | X | + | 20057 500 |
| X | − | 1 20 | X | = | 20057 500 |
19 20 | X | = | 20057 500 |
| X | = | 20057 500 | ÷ | 19 20 |
| = | 20057 500 | × | 20 19 |
| = | 20057 25 | × | 1 19 |
| X | = | 20057 475 |
