Answer 2

Answer:

x=1

Explanation:

given,

148/x + 231 /y = 527/xy

231/x + 148/y = 610/xy

multiply both eqn with 'xy' , we get

148y + 231x = 527 -------------------( 1 )

231y + 148x = 610 ------------------ ( 2 )

multiply (1 ) by 148 and ( 2 ) by 231 , we get

34188x + 21904y = 77996 -------------( 3 )

34188x + 53361y = 140910 ------------( 4 )

subtracting ( 3 ) from ( 4 ) , we get

53361y _ 21904y = 140910 _ 77996

31457y = 62914

y = 2

put ' y = 2 ' in ( 1 )

231 x + 148 (2) = 527

231 x = 527 _ 296

231 x = 231

x = 1

hence proved
