Alright guys.. I asked for help with this problem a few weeks ago, and I just received the graded worksheet. I liked what you guys did with this, I thought it was clever. But, apparently, this wasn't the answer the lady was looking for because it's marked completely wrong. I'm about to start trying to figure it out myself, but I can always use some help from you guys. So my question is: Is there any way to work through this using only the left side? Starting with and, changing only that, showing that it equals ?
Thanks! and sorry to ask again.
