To solve this equation in terms of y, we must isolate it. We start by moving those terms, that do not involve y, to the right hand side. Thus, we add 6 to both sides.
Next, since there are no other terms on the left hand side that do not include y, we must factor a y out of them.
Now, we can divide to isolate y.
