19 100 | ( | X | − | 60 | ) | + | 18 | = | 0 |
| Left side of the equation = | 19 100 | X | − | 19 100 | × | 60 | + | 18 |
| = | 19 100 | X | − | 57 5 | + | 18 |
| = | 19 100 | X | + | 33 5 |
19 100 | X | + | 33 5 | = | 0 |
19 100 | X | = | 0 | − | 33 5 |
19 100 | X | = | - | 33 5 |
| X | = | - | 33 5 | ÷ | 19 100 |
| = | - | 33 5 | × | 100 19 |
| = | - | 33 | × | 20 19 |
| X | = | - | 660 19 |
| X | = | - 34.736842 |
