I have a file similar to the following :

x 0
1 x
1 1

and I am essentially trying to see if both fields are equal to one another or not for every row. But the problem is that this file contains x which can either hold the value of 0 or 1 -- but I am not sure how to set this in awk

I tried working with the following code that did not work, it only works if x is set to either 0 or 1, not both.

y=$(seq 1 2)
awk -v x="$y" '{ if ($1==$2) print "good" }' file

Please advise or let me know if any clarification is necessary, thank you.

A scalar variable in awk can only hold a single variable. You'll have to do something like this:

if (
    ($1 == "x" && ($2 == 0 || $2 == 1)) ||
    ($2 == "x" && ($1 == 0 || $1 == 1)) ||
    $1 == $2
) print "good"
