Answer 4

ok thanks

Answer 5

your answer will have a \(y\) in it i believe
a one answer could be both are 0
which you can see by inspection
another you might try is both are 2

Answer 6

if you start with
\[xy=x+y\] you can solve for \(x\) by writing
\[xy-x=y\]
\[x(y-1)=y\]
\[x=\frac{y}{y-1}\] so if you pick any \(y\) you can find the corresponding \(x\)

Answer 7

well these are the choices:
a) y+1/y-1
b) y+1/y
c) y/y-1
d) y/y+1
e) 1-1/y

Answer 8

ok then use the answer above

Answer 9

or just go with C because it is almost always C
in fact C is right in this case (as usual)
