Hockey teams receive 2 points for a win and 1 point for a tie. The Wildcats once won a championship with 60 points. They won 9 more games than they tied. How many wins and how many ties did the Wildcats have?
I'm a little unsure about this one. Are these the correct equations?
Equation #1: 2x + 1y = 60
Equation #2: x + y = z+9
The second equation I am especially unsure of. What is the correct equation, or am I correct. I am assuming that z is the number of games they tied.

As I stated in one of my other replies to you, it is very important that you define your variables.
let the number of wins be x
let the number of ties be y
"They won 9 more games than they tied" > x = y + 9 or x  y = 9
Your other equation is correct.
