| X | ÷ | 126 | + | ( | 26 | − | X | ) | ÷ | 111 | − | 27 500 | = | 1667 10000 |
| Left side of the equation = | 1 126 | X | + | 26 | × | 1 111 | − | X | × | 1 111 | − | 27 500 |
| = | 1 126 | X | + | 26 111 | − | X | × | 1 111 | − | 27 500 |
| = | - | 5 4662 | X | + | 10003 55500 |
| - | 5 4662 | X | + | 10003 55500 | = | 1667 10000 |
| - | 5 4662 | X | = | 1667 10000 | − | 10003 55500 |
| - | 5 4662 | X | = | - | 15023 1110000 |
15023 1110000 | = | 5 4662 | X |
5 4662 | X | = | 15023 1110000 |
| X | = | 15023 1110000 | ÷ | 5 4662 |
| = | 15023 1110000 | × | 4662 5 |
| = | 15023 185000 | × | 777 5 |
