( | P | − | 700 | ) | × | 20000 | − | 3400000 | = | 400000 | − | P | × | 20000 |
Left side of the equation = | P | × | 20000 | − | 700 | × | 20000 | − | 3400000 |
= | P | × | 20000 | − | 14000000 | − | 3400000 |
= | 20000 | P | − | 17400000 |
20000 | P | − | 17400000 | = | 400000 | − | P | × | 20000 |
20000 | P | + | 20000 | P | = | 400000 | + | 17400000 |
40000 | P | = | 400000 | + | 17400000 |
40000 | P | = | 17800000 |
P | = | 17800000 | ÷ | 40000 |
= | 17800000 | × | 1 40000 |
= | 445 | × | 1 |
P | = | 445 |
