The solution to the system of equations is $x = -5$ and $y = 8$.

Would you like further details or have any questions?

Here are 5 related questions you might explore:

1. How does substitution compare to other methods like elimination?
2. What happens if both equations are expressed in terms of $y$?
3. Can you solve a system of equations with three variables using substitution?
4. What is the graphical interpretation of solving this system?
5. How would you solve the system if both equations were non-linear?

Tip: Always double-check your substituted values by plugging them back into the original equations.
