| ( | 2146 | − | X | ) | ÷ | X | = | 11 100 |
| Multiply both sides of the equation by: | X |
| ( | 2146 | − | X | ) | = | 11 100 | X |
| 2146 | − | X | = | 11 100 | X |
| - | X | − | 11 100 | X | = | - | 2146 |
| - | 111 100 | X | = | - | 2146 |
| 2146 | = | 111 100 | X |
111 100 | X | = | 2146 |
| X | = | 2146 | ÷ | 111 100 |
| = | 2146 | × | 100 111 |
| X | = | 214600 111 |
| X | = | 5800 3 |
| X | = | 1933.333333 |
