As one of the organizers of the OAME 2022 conference I'm excited about our slate of keynote and featured speakers. On the latest @OAMEtalks podcast they all answer the question "What did you do while online that you will continue to do as we move to more face to face?". Have a listen and then register for the conference. More info here http://oame2022.ca/

Can your Algebra students create a a system of three equations with a solution at (1, 1)? Try out this challenging@openmiddle problem from @Audrey_Mendivil, @danluevanos, and me with them. https://t.co/fL1rSJLZPx #iteachmath pic.twitter.com/PJ65qzWXrf

I did some work showing something similar in this @Desmos activity but this video does a nice job of explaining why you can't use SSA (in general).

Actually, infinitely many such equations can be framed.

We can start with unknown values x, y & z.
I'm not mentioning every step rigorously here, but it's enough to figure out.
The final equation on left implies x=y and z=x²-1.
Hence, we get values for all x>1 pic.twitter.com/o8DKe8fO0j
