Hey there!
We are assuming the number be [tex] a [/tex]
So, let's solve this problem, shall we?
Firstly, we would have to [tex] divide [/tex] by [tex] -9 [/tex] on each of your sides
[tex] \frac{-9a}{9} = \frac{-72}{-9} \\ \\ Cancel: -9a And-9 \\ \\ Keep: -72And 9 \\ \\ \\ \frac{-72}{9} = -8\\ \\ \\ Product/ Answer: -8 [/tex]
The number that is multiplied by [tex] 9 [/tex] that gives you [tex] -72 [/tex] would most likely be: [tex] -8 [/tex]
Good luck on your assignment and enjoy your day!
