Question

20) Solve the equation:- p/(p+15)=4/9​

Answer 1

ANSWER✔

$\sf\dashrightarrow \dfrac{p}{p+15} = \dfrac{4}{9}$

$\sf\implies 9 \times (p)= 4 \times (p+15)$

$\sf\implies 9p=4p+60$

$\sf\implies 9p-4p= 60$

$\sf\implies 5p= 60$

$\sf\implies p= \dfrac{60}{5}$

$\sf\implies p= \cancel\dfrac{60}{5}$

$\sf\implies p= 12$

$\large{\boxed{\bf{ \star\:\: p=12\:\: \star}}}$

Answer 2

$\huge{\underline{\color{purple}{\mathfrak{Answer:}}}}$

$\implies\sf\dfrac{p}{p + 15} = \dfrac{4}{9}$

$\implies\sf \: p \times 9 = 4 \times (p + 15)$

$\implies\sf9p = 4p + 60$

$\implies\sf9p - 4p = 60$

$\implies\sf5p = 60$

$\implies\sf \: p = \dfrac{60}{5}$

$\implies\sf \: p = 12$
