Question

Choose the correct answer and Fill in the blanks:

$\left(-4\right)+\left(\_\_\_\right)=\left(-12\right).\left[\left(-8\right)/\left(+8\right)\right]$

Answer 1

If we substitute $-8$ we get

$$\begin{gathered} \left(-4\right)+\left(-8\right) \\ -4-8 \\ =-12 \end{gathered}$$

Hence, $\left(-4\right)+\left(-8\right)=-12$
