So, basically, I'm supposed to solve a word problem using substitution. It's kinda difficult for me, hence, why I'm here. The instructions are: 

1. Define variables x and y

2. Set up a system of equations modeling the situation

3. Solve the system using substitution. Show steps. 

After each word problem, it says: Let x =           and                Let y =
