Answer :
Finding an unknown variable
We need to find a
[tex]96=-24a[/tex]We divide by -24 both sides:
[tex]\frac{96}{-24}=\frac{-24}{-24}a[/tex]Since
[tex]\begin{gathered} \frac{96}{24}=4\text{ and } \\ \frac{-24}{-24}=1.\text{ Then},\text{ replacing both values in the previous equation} \\ -4=1a=a\text{. Then} \\ a=-4 \end{gathered}[/tex]Answer: a = -4
