I have the following relation T on $N\times N$ given by $(a, b)T(c, d)$ if $a + b = c + d$. The question is to find the equivalence class of the number 2. However, I'm confused as the relation takes pairs of numbers. Is it possible? Do we find all combination of a and b that add to 2? Any help would be appreciated.

What is the equivalence class of the number 2 when the relation takes two inputs?
