will someone please double check my answer to this problem. the answer i get is a fraction, but not sure how to type it on here.
divide both by 12 and that leaves y=14/12 then reduce down to 7/6
is this correct?

Your mistake here is when you go from
16y + 8 = 10 + 12y
8 = -6 + 12y.
You aren't subtracting the same thing from both sides; you're subtracting 16y from the left, but 16 from the right. Assuming you mean to subtract 16y, you should end up with
8 = 10 - 4y
Subtract 10 from each side:
-2 = -4y
Multiply each side by -1/4:
1/2 = y.
