x+1/y=1 & y+1/z=1
then z+1/x=?
Read Solution (Total 3)
-
- x+(1/y)=1 so (1/x) = y/(y-1)
y+(1/z)=1 so z = 1/(1-y)
Hence z+(1/x) = ( 1/(1-y) ) + ( y/(y-1) ) = (y-1)/(y-1) = 1
Answer is z+(1/x) = 1. - 9 years agoHelpfull: Yes(3) No(0)
- x=1-(1/y) then 1/x=y/y-1--------(1)
similarly,1/z=1-y then z=1/(1-y)-------(2)
on adding(1)&(2).........z+(1/x)=1 - 9 years agoHelpfull: Yes(0) No(0)
- x+1/y=1
so
z+1/x=1 - 9 years agoHelpfull: Yes(0) No(0)
