Explanation:

#{ (y < 2x + 4), (2x - y<=4) :}#

First of all you should reorder every variable:
#{(y < 2x + 4), (y >= 2x - 4) :}#

As you can see from the graph, the two solutions of the inequalities are two surfaces. The first is "everything below the line" and the second disequation is "everything above the line".
