11 2000 | X | + | ( | 80 | − | X | ) | ÷ | 111 | = | 119 1000 |
| Left side of the equation = | 11 2000 | X | + | 80 | × | 1 111 | − | X | × | 1 111 |
| = | 11 2000 | X | + | 80 111 | − | X | × | 1 111 |
| = | - | 779 222000 | X | + | 80 111 |
| - | 779 222000 | X | + | 80 111 | = | 119 1000 |
| - | 779 222000 | X | = | 119 1000 | − | 80 111 |
| - | 779 222000 | X | = | - | 66791 111000 |
66791 111000 | = | 779 222000 | X |
779 222000 | X | = | 66791 111000 |
| X | = | 66791 111000 | ÷ | 779 222000 |
| = | 66791 111000 | × | 222000 779 |
| = | 66791 | × | 2 779 |
| X | = | 133582 779 |
