Question

solve for the variable p :
$\frac{p}{2} + \frac{p}{4} + \frac{p}{5} + 10000 = p$

Answer 1

$\frac{p}{2} + \frac{p}{4} + \frac{p}{5} + 10000 = p \\ ( \frac{p}{2} + \frac{p}{4} ) + \frac{p}{5} + 10000 = p \\ \frac{3p}{4} + \frac{p}{5} + 10000 = p \\ (\frac{3p}{4} + \frac{p}{5} ) + 10000 = p \\ \frac{19p}{20} + 10000 = p \\ p - \frac{19p}{20} = 10000 \\ \frac{p}{20} = 10000 \\ p = 20 \times 10000 = 200000$
