(E) y = 0


\(y+|y| = 0\) --> \(|y|=-y\). Now, LHS is an absolute value which is never negative hence RHS must also be non-negative: \(-y\geq{0}\) --> \(y\leq{0}\).

Or you can see right away that in order \(y+|y|=0\) to hold true y must be either negative number (for example -3+|-3|=0) or zero (0+|0|=0).

Answer: D.

y must be negative and zero since positive y will give non-zero results

The difference is that C just implies that Y <0, where as D says Y < 0 or Y = 0.

If you plug values in as Y = 0, it will satisfy the equation.
