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.
4(4y+2)=2(1+6y)+8
16y+8=2+12y+8
16y+8=10+12y
16 16
8=6+12y
+6 +6
14=12y
divide both by 12 and that leaves y=14/12 then reduce down to 7/6
is this correct?

12

i don't know how you are getting this answer. can you explain to me what i need to do please. thanks ive been out of school since 1995 and i never took algebra in high school so im having a tough time in college.

Your mistake here is when you go from
16y + 8 = 10 + 12y
to
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. 
okay i worked through this problem but at the end, i need to multiply? I thought i divided both by 4?
