Question

Solve : xy/x+y =6/5
​

Answer 1

Answer:

Xy/(x + y) = 6/5

⇒ (x + y)/xy = 5/6 [ take reverse ]

⇒ x/xy + y/xy = 5/6

⇒ 1/y + 1/x = 5/6 --------(1)

again, xy/(y - x) = 6

⇒(y - x)/xy = 1/6 [ take reverse ]

⇒y/xy - x/xy = 1/6

⇒ 1/x - 1/y = 1/6 -------(2)

add equations (1) and (2) ,

(1/y + 1/x ) + (1/x - 1/y) = 5/6 + 1/6

⇒ 2/x = (5 +1)/6

⇒ 2/x = 1 ⇒ x = 2 , put it in equation (1)

1/y + 1/2 = 5/6

⇒1/y = 5/6 - 1/2 = (5 - 3)/6 = 1/3

⇒ y = 3

ur answer is x = 2 and y = 3
