Question 646617
<font face="Times New Roman" size="+2">


The fact that both variables are positive makes your feasibility area in the first quadrant.


Now, one at a time, change each of the other inequalities to an equation and graph the line.  Once you have the boundary line graphed, you need to figure out which side of the line to shade.  Since neither of the lines go through the origin, you can use the origin as your test point for each inequality.  You replace x and y with zeros in both inequalities.  If you make a true statement, shade in the side with the point (0,0) in it, otherwise shade in the other side.  Where the shaded areas overlap in the first quadrant you have an area of feasibility.


The problem is that this problem either has no answer or you have the inequality sign pointed the wrong way on the 5 <= y + x inequality or you really want to minimize your objective rather than maximize it.


While we are at it, it really doesn't make much sense that there is no y variable in the objective function.
