yup E is the answer .....spot on titleist!!!!!
just had a another doubt ........ if x= -y ......then the y can take a positive as well as negative value is it ? .........uve taken 3 and -3
yes, y can be either positive or negative thus effecting the sign of x.
if y =3, then x=-3
if y=-3, then x=3
I just used 3 but, of course, you can use any number (doesn't even have to be an integer, according to the problem) you want.
i hope i've answered your question.
