| 150 | = | 56 | ÷ | ( | 6 | − | x | ) |
| Multiply both sides of the equation by: | ( | 6 | − | x | ) |
| 150 | ( | 6 | − | x | ) | = | 56 |
| 150 | × | 6 | − | 150 | x | = | 56 |
| 900 | − | 150 | x | = | 56 |
| - | 150 | x | = | 56 | − | 900 |
| - | 150 | x | = | - | 844 |
| 844 | = | 150 | x |
| 150 | x | = | 844 |
| x | = | 844 | ÷ | 150 |
| = | 844 | × | 1 150 |
| = | 422 | × | 1 75 |
| x | = | 422 75 |
| x | = | 5.626667 |
