8y - 12 + 6y = 6y + 6
14y - 12 = 6y + 6
14y - 6y = 6 + 12 <- bring like terms togethor
8y = 18
8y/8 = 18/8
y = 2.25

Doesn't seem like the answer you were looking for.

I just quote the answer from this guy from the first page xD

8y-12+6y=6y+6
14y-12= 6y+6
-12= -8y+6
-18=-8y
y = -18/-8 = 2.25
there

Fix'd, in the bold is what I changed for you.

edit: oh snaps nevermind. Moshi already did it.

This is how i learned how to do it.
8y-3(4-2y) = 6(y+1)
8y-12-6y = 6y+6 <---- Dist. Property
-12-2y = 6y+6
+2 +2 <---- +2 on both sides
________________________
-12 = 8y+6
-6 -6 <---- -6 on both sides
________________________
-18 = 8y
/8 /8 <---- Divide by 8 both sides
________________________
-2.25 = y

y = -2.25

It looks long cuz i showed all steps but i can do it mentally
