    yes, y-2y+2 the sign is important! anyway, you can rewrite y-2y+2 as -y+2

    That's an answer! Thank you! You're my favorite, you're one of the few who actually explains and lets me do the work at the same time thank you

    your answer is wrong, check which way the < sign is pointing

  33. Jravenv

    So Y < 10?

    yes, do you understand why?

    also, check your sign on 10

    Because when you multiply a negative you have to swap the directions. so it's y<-10
