| X | ÷ | 4 | = | ( | 1 2 | − | X | ) | ÷ | ( | 1 | ÷ | 4 | ) |
| Multiply both sides of the equation by: | ( | 1 | ÷ | 4 | ) |
| X | ÷ | 4 | × | ( | 1 | ÷ | 4 | ) | = | ( | 1 2 | − | X | ) |
| X | ÷ | 4 | × | 1 | ÷ | 4 | = | ( | 1 2 | − | X | ) |
| X | ÷ | 4 | × | 1 | ÷ | 4 | = | 1 2 | − | X |
| X | × | 1 16 | = | 1 2 | − | X |
1 16 | X | + | X | = | 1 2 |
17 16 | X | = | 1 2 |
| X | = | 1 2 | ÷ | 17 16 |
| = | 1 2 | × | 16 17 |
| = | 1 | × | 8 17 |
| X | = | 8 17 |
| X | = | 0.470588 |
