Answer 1

Answer:

21/x +47/y=110

47/x+21/y=162

let 1/x be p and 1/x=q

21p+47q=110  (1)

47p+21q=162  (2)

(2)-(1)

⇒26p-26q=52

⇒p-q=2  (3)

(2)+(1)

⇒68p+68q=272

⇒p+q=4

adding 3 and 4

⇒2p=6  ⇒p=3

(4)-(3)

⇒ 2q=2  ⇒q=1

1/x=p=3                                      1/y=q=1

x=1/3                                           y=1
