Guys i need the answers to number 16

#16:  Let's clear the fraction on the way to solving this inequality for x.  By mult. the given inequality by 2, we'll get -2 (is greater than) x+4.  We want x to be positive.  So, leave it where it is.  Subtract 4 from both sides of this inequality.  We end up with -6 (is greater than) x, which is the same thing as x (is less than) -6.  What would the graph of that simple inequality look like?

Graph it.  (Hint:  The graph is a straight dashed line, and you must shade one side of it, but not the other side.
