This is explained in the solution. The inequality 5y > 0 doesn’t depend on any particular example like 3 > -2; it comes directly from simplifying the given expression. When 5y > 0, dividing both sides by 5 gives y > 0. The example 3 > -2 isn’t relevant here because it doesn’t satisfy the algebraic relation that leads to 5y > 0.

Hi Team,
I assumed x = x and y = x-1 and substituted x-1 in all the places where y appears in the equation. this gave me the final value as x > x-5.
Is there any inference I can draw about y post this, i'm unable to comprehend the equation in terms of y after this point

First, notice that the answer choices are asking for a conclusion about y, not about x. So it is better to rewrite everything in terms of y from the start by using x = y + 1 (as in the official solution). That way, you end up with an inequality directly in y, which matches what the question is testing.
Second, even if you continue with your approach, you should not get x > x - 5. You should get x > 1. Then, since x = y + 1, we have y + 1 > 1, which implies y > 0, exactly the same inequality as in the official solution.
