anyhow I am wondering what you are taking away from all the answers youve been getting. are you learning how to do this stuff?

17. Natz0213 Group Title

yes i have learned a lot from this website i just have a hard time grasping it .It takes me to learn it mre than once before i got it all the way

your answer is 5x-10y use difference of squares to simplify into: $(5x+10y)(5x-10y)\div(5x+10y)$ (5x+10y) crosses out from the equation because $(5x+10y)\div(5x+10y)=1$ so you are left with 5x-10y
