| - | 50 | − | ( | 100 | + | X | ) | × | 1 100 | + | X | = | 0 |
| Left side of the equation = | - | 50 | − | 100 | × | 1 100 | − | X | × | 1 100 | + | X |
| = | - | 50 | − | 1 | − | X | × | 1 100 | + | X |
| = | - | 51 | + | 99 100 | X |
| - | 51 | + | 99 100 | X | = | 0 |
99 100 | X | = | 0 | + | 51 |
99 100 | X | = | 51 |
| X | = | 51 | ÷ | 99 100 |
| = | 51 | × | 100 99 |
| = | 17 | × | 100 33 |
| X | = | 1700 33 |
| X | = | 51.515152 |
