| 10 | − | X | + | ( | ( | 6 | − | 7 | X | ) | ÷ | 11 | − | X | ) | = | 0 |
| Left side of the equation = | 10 | − | X | + | ( | 6 | − | 7 | X | ) | ÷ | 11 | − | X |
| = | 10 | − | 2 | X | + | ( | 6 | − | 7 | X | ) | × | 1 11 |
| = | 10 | − | 2 | X | + | 6 | × | 1 11 | − | 7 | X | × | 1 11 |
| = | 10 | − | 2 | X | + | 6 11 | − | 7 11 | X |
| = | 116 11 | − | 29 11 | X |
116 11 | − | 29 11 | X | = | 0 |
| - | 29 11 | X | = | 0 | − | 116 11 |
| - | 29 11 | X | = | - | 116 11 |
116 11 | = | 29 11 | X |
29 11 | X | = | 116 11 |
| X | = | 116 11 | ÷ | 29 11 |
| = | 116 11 | × | 11 29 |
| = | 4 | × | 1 |
| X | = | 4 |
