How can I transform the equation 4=x-y into one that begins with "y="?

Would I subtract x from both sides to get -x+4=-y? This doesn't look right at all.

Or would I add y to both sides and then subtract 4 to get y=x-4? This way seems more correct to me.

Please confirm which way is correct... thanks very much.
