Question

The missing member '$x$' in the ordered pair ($x,-8$) if the second member of the pair is four more than the first member is

• A. $-4$
• B. $-8$
• C. $-12$
• D. $4$

Answer 1

The correct option is C

$-12$

Explanation for the correct option:

Finding the missing member $x$:

As we can see that, the first member of ($x,-8$) is $x$ and the second member is $-8$

Given that the second member of the pair ($x,-8$) is four more than the first member.

Hence, the equation can be written as

$-8=4+x....\left(i\right)$

Simplifying equation $\left(i\right)$, we get

$$\begin{gathered} \Rightarrow x=-8-4 \\ \Rightarrow x=-12 \end{gathered}$$

Thus, value of $x$ is $-12$.

Hence the correct answer is option (C).
