| ( | X | − | X | ÷ | 113 100 | × | 13 100 | + | 11 1000 | ) | = | 7 100 |
| Left side of the equation = | X | − | X | ÷ | 113 100 | × | 13 100 | + | 11 1000 |
| = | X | − | X | × | 13 113 | + | 11 1000 |
| = | 100 113 | X | + | 11 1000 |
100 113 | X | + | 11 1000 | = | 7 100 |
100 113 | X | = | 7 100 | − | 11 1000 |
100 113 | X | = | 59 1000 |
| X | = | 59 1000 | ÷ | 100 113 |
| = | 59 1000 | × | 113 100 |
| X | = | 6667 100000 |
| X | = | 0.06667 |
