How would you go about finding the solution to this system of three equations in three variables? Be specific. For example, you might want to add the first two equations first, or multiply the third one by two first and use elimination, etc. (No right answer exists.) Read your classmates' methods, and try to come up with a different approach. Remember to be respectful when commenting on your classmates’ ideas.

2x – y + z = 7
x + 2y – 5z = -1
x – y = 6
