| 5 | p | ( | - | p | − | 5 | + | 3 | ÷ | p | ) | + | 5 | × | 3 | ( | - | p | − | 5 | + | 3 | ÷ | p | ) | = | 6 5 |
| 5 | p | ( | - | p | − | 5 | + | 3 | ÷ | p | ) | + | 15 | ( | - | p | − | 5 | + | 3 | ÷ | p | ) | = | 6 5 |

| - | 5 | p | p | − | 40 | p | − | 60 | + | 45 | ÷ | p | = | 6 5 |
| Multiply both sides of the equation by: | p |
| - | 5 | p | p | p | − | 40 | p | p | − | 60 | p | + | 45 | = | 6 5 | p |
