    Hello,

    |x-3| > 0 for x != (means unequal) 3

    if y > 0 the RHS of the inequality is lower than zero.

    There is only one possibility that this inequality is satisfied: If x = 3 and y = 0

    If y>=0 then -y<=0.
    If -y<= then no matter what x you chose it will work because |x-3|>=0.

    So -y=0. Meaning |x-3| = 0 so, x=3
