P | + | P | ÷ | ( | 4 | − | 1 | ) | = | 19 |
Multiply both sides of the equation by: | ( | 4 | − | 1 | ) |
P | ( | 4 | − | 1 | ) | + | P | = | 19 | ( | 4 | − | 1 | ) |
P | × | 4 | − | P | × | 1 | + | P | = | 19 | ( | 4 | − | 1 | ) |
P | × | 4 | − | P | × | 1 | + | P | = | 19 | × | 4 | − | 19 | × | 1 |
P | × | 4 | − | P | × | 1 | + | P | = | 76 | − | 19 |
4 | P | = | 57 |
P | = | 57 | ÷ | 4 |
= | 57 | × | 1 4 |
P | = | 57 4 |
P | = | 14.25 |
