Apologies

Hey guys,
Today was a sad day. As you may have noticed, I was a little flustered in class. You may be wondering why this is. The truth is, I lost my pink chalk. This chalk was very important for me. As you may know I traded my sanity/marbles for it. Without either of these things I could not remember how to solve a series of linear equations with three variables and only three equations. However today was especially hard because the chalk gnomes were mean and put different types of chalk inside my chalk. I had yellow on the outside and white on the inside, and orange outside and yellow inside, yellow every where, it was bad. I promise you all that I will again find my pink chalk and redeem myself.
Best,
Papa Mattuck
