Question

find the value of y using componendo and dividendo rule y+5 upon y-5=2 upon 3​

Answer 1

Answer:

y = -25

Step-by-step explanation:

$\frac{y+5}{y-5} = \frac{2}{3}$

using comp. & div.

$\frac{(y+5)+(y-5)}{(y+5)-(y-5)} = \frac{2+3}{2-3}$

$\frac{y+5+y-5}{y+5-y+5} = \frac{5}{-1}$

$\frac{2y}{10} = -5$

$2y = -5 *10$

$2y = - 50$

$y = \frac{-50}{2}$

$y = -25$
