NOTE: I will post this problem early, so I will not be posting another problem on Saturday.
If x2-y2=17, x>y, and x and y are both whole numbers greater than 0. What is xy?

Um, I just messed around with the calculator until I got 9 and 8 as x and y. Then I multiplied them together. I am not very good on writing equations; so I usually try and figure it out in other ways. 😉

Fair enough! Good job for getting it right!

I really need to work on my equations though, because I am taking the PSAT next week! 😬

Yes, that is very important. I took the PSAT test and I didn’t do the best on the math. I spent too much time on problems I had a difficult time with, when I should have kept going and coming back to it later. Also, do any multiple choice problems last, because if you run out of time you can quickly guess on them with some hope of getting it right. Just a couple tips I thought would be helpful. Hope the test goes well!
