In my approach,

##y=6-x##

##x^2(6-x)^2+2x(6-x)-35=0##

...

##x^4-12x^3+34x^2+12x-35=0##

using factor theorem, i noted that ##f(1)=0## therefore ##(x-1)## is a factor.

on long division we also have other factors:##(x+1), (x-5)## and ##(x-7)## from these we can find ##y## values by using ##y=6-x##. This may be the only approach ....quite easy this one.
