SOLUTION FOR QUESTION NO.-1
Since it is given that x>y>0 & 2x=2y=13
=>2(x+y)=13
=>x+y=13/2-(1)
Since it is also given that xy=6 =>y=x/6
putting the value of y in (1):-
x+6/x=13/2
2xsq+12=13x
2xsq-13x+12=0
x=13+_under root(73)
----------------------- >0
4
now, putting the value of y in (2) we get:-
y=24
--------------------- >0
13+_under root(73)
