try to solve the problem, coocoocharlie

Answer 3

You know, if those inequalities (>,<,\(\ge\),\(\le\)) were = signs instead, the graph would be pretty much the same, except no shading, no broken lines. Just two lines which intersect at (2,3).

So... if you replace each system of inequalities with their corresponding system of equations, just select the system with (2,3) as its solution...

There may be more than one of them though... if there are, come back to me on that :)
