i dont even get where to start, everything i learned in algebra so far would tell me to distribute that 2 into the (x+y) or at least add that 2 and 1 together through communative property, but on my little algebra helper program it goes a different route that iam not familiar with and the answer doesnt make sense to me, was hoping for a human to explain it step by step, thanks for any help
