xyz not equal to 0 is x(y+z)=0?
1) |y+z|= |y|+ |z|
2) |x+y|= |x| + |y|
Shouldnt this be A?
Can't be A, because we have no info about x.
Yeah but since from the question stem x can't equal zero, and from statement 1 y and z have the same sign, the value of x shouldn't matter right? The expression can't be equal to zero?
I take that back Apollo. You are right, x can`t be 0. In (A), even if they are the same or different integers, then we can definitively answer this question ---No.
