To determine the missing number:

$\text{Let the missing number = x}$
$\begin{gathered} 6\text{ times a number = 6x} \\ 6x+(-3)=9x \\ 6x-3=9x \end{gathered}$

collect like terms

$\begin{gathered} 6x-9x=3 \\ -3x=3 \\ \text{divide both side by -3} \\ -(3x)/(-3)=(3)/(-3) \\ x=-1 \end{gathered}$

Therefore the missing number = -1
