| ( | ( | 50 | − | p | ) | × | 17 20 | + | 3 | × | 7 10 | ) | ÷ | p | = | 17 100 |
| Multiply both sides of the equation by: | p |
| ( | ( | 50 | − | p | ) | × | 17 20 | + | 3 | × | 7 10 | ) | = | 17 100 | p |
| ( | 50 | − | p | ) | × | 17 20 | + | 3 | × | 7 10 | = | 17 100 | p |
| ( | 50 | − | p | ) | × | 17 20 | + | 21 10 | = | 17 100 | p |
| 50 | × | 17 20 | − | p | × | 17 20 | + | 21 10 | = | 17 100 | p |
85 2 | − | p | × | 17 20 | + | 21 10 | = | 17 100 | p |
223 5 | − | 17 20 | p | = | 17 100 | p |
| - | 17 20 | p | − | 17 100 | p | = | - | 223 5 |
| - | 51 50 | p | = | - | 223 5 |
223 5 | = | 51 50 | p |
51 50 | p | = | 223 5 |
| p | = | 223 5 | ÷ | 51 50 |
| = | 223 5 | × | 50 51 |
| = | 223 | × | 10 51 |
| p | = | 2230 51 |
| p | = | 43.72549 |
