    Well... \[\large 5 - \frac{y}{8} = \frac{8}{8} \times 5 - \frac{y}{8} = \frac{40}{8} - \frac{y}{8} = \frac{40 - y}{8}\] I actually don't think either are correct there hun :/ But do you see what I did?

    Find the common denominator first...then carry out the subtraction

    I did the same thing in my first one but thought it was negative,

    Nope...that '5' never becomes negative to begin with...the common denominator is 8...so after you multiply the 5 by 8/8 you get that 40/8 term...but no negative :)

    Well yes and no...you'll actually be able to carry out the addition this time

    so the mixed number would be the answer?

    Hmm, theoretically yes...but I hardly ever see a software or a teacher wanting a mixed number as the answer...probably just leave it as an improper fraction \[\large -\frac{31}{6}\] if my quick mental math is right
