If v and w are different integers, does v=0?
statement 1: vw=v^2
statement 2: w=2
[spoiler]Statement 1 is sufficient because
vw=v^2
vw - v^2 = 0
v (w -v) = 0 but w is different from v so v=0
However, what if v=-3 and w=3 ? It should be (-3)(3)=9 and v wouldn't be zero.[/spoiler]
Could you please clarify? Thanks.
