A point that satisfies the criteria is (4,5) p=31.
You determine which one to use by seeing which one would be easier
elimination: 5x + 7y = 2
-5x + 6y = 6
substitution: y = 9x + 5
2y = 7x + 2
answer: an equation is a set of numbers put together within a problem that you are meant to solve in order to receive the final answer.
