Hi, is there anyone who can help me?
the question:
if (5zx)/(z+x)= 3 & (4yz)/(y+z)=5 & (3xy)/(x+y)=4 ,
then 1/x + 1/y + 1/z =?
i tried two ways but i couldn't find the answer. once, i changed fractions to equivalent fractions having same denominator. but it doesn't seem to help.
then I Invert the fractions , but it didn't help either.
I really don't know how to solve it.
