Answer 1

It looks like you've provided a system of equations and the solution to it. The given system of equations is:

1. $x + y = 15$
2. $y + 4 = 2(x - 4)$

You've correctly solved the system and found that the solution is $x = 9$ and $y = 6$. Your step-by-step explanation shows how you arrived at these values. Well done! If you have any further questions or need assistance with anything else, feel free to ask.
