Answer:
See below:
Step-by-step explanation:
We can first setup an equation!
We know the order since the word problem has told us.
[tex](x-15)*-6=-144[/tex]
We can now simplify it, first, we can divide by -6 on both sides.
We now get:
[tex](x-15)=24[/tex]
Now, we can add 15 on both sides to get our answer.
[tex]x=39[/tex]
We can insert that in and we will get the same answer.
