Might be wrong sorry
open the parenthes. and then after that you'll get 27+12x-15. if you simplify that then you'll get 12x+12
I'm pretty sure it would go between 8 and 10 if it's 9 sports books it would go between 8 an 10
Answer:

Step-by-step explanation:
We are given a system of equation:

To find a solution to the given system, we follow the given steps.
1. Subtracting second equation from first and third equation, we get:

2. After eliminating z to obtain two equations in two variable, we observe that the two equations obtained were same.
So we have three equations that will all graph in the same plane.
Thus, there are infinite number of solution to the given system of equation.
We can write the values of x and y in the form of z:
