Question

If $x+y=0$, then $-y$ is known as the negative of $x$, where $x$ and $y$ are rational numbers. State whether the statement is

• A. True
• B. False

Answer 1

The correct option is B False

Determine using example:

If $x$ and $y$ are rational numbers,then

$$\begin{gathered} \Rightarrow x+y=0 \\ \Rightarrow x=-y \end{gathered}$$

Thus,$-y$ is positive of $x$

Example: Let $x=\frac{2}{3}$ then, $x=-y$, we get

$\Rightarrow -y=\frac{2}{3}$

Therefore, the given statement is False.
