that's correct, we should rewrite w<-x as -w>x

W < -X --- >> to ---- >> W > X,

I thought if we multiply by -1 , then we have to multiply both the sides of the equations and reverse the inequality ??

so in thi case: W < -X should not it be converted to -W > X ???

Here we are given different conditions w<-x and w>x OR -w>x and w>x. We can further deduct that x<0 and w<|x|. BUT the question is asking about y? Precisely, the question is w>y? Please check with your book again as from this we cannot answer this question, and if this is DS question then the answer is E. If this is not DS question, we need the relationship between x and y ...

Thanks a lot.

Sorry the question was something else in GMAT Prep. I will procide the link once I am able to find.

Here is the question:

Thanks.

the question is;


Can I convert W < -X

to -W > X ? - is this correct ?

I have posted solution to this DS question in the relevant forum today. I have also arrived at different answer - E.
