(x1, y1)Υ(x2, y2) ⇔ x1 × y2 = x2 × y1
for all x1, x2 ∈ Z and y1, y2 ∈ Z+ have been shown to be an equivalence relation in tutorial.
Specify the equivalence class [(2; 3)] as induced by Υ.
i don't understand what it means by 'Specify the equivalence class [(2; 3)] as induced by Υ.'
can anyhone guide me along?
