Today we started with a warm up on the different solution types we could get from graphing: 1 solution, no solution, or infinite solutions. Then, we practiced solving by substitution. I showed Ben that just like graphing, there are 3 different solution types when solving with substitution. We worked together to solve the first system and found a value for x which we used to then find y. In the second problem we did, we worked to solve for x but then ended up getting 4=-4. I explained to Ben that is when we have "no solution" because we end up with a false statement. Lastly, we did a problem where when we tried to solve for x we got 7=7. Since that is a true statement, that would yield us infinitely many solutions. He did a great job understanding and relating the two concepts.
