I never understood the system of inequalities and using a graph, help?

Plot the graph as if there were an equal sign instead of > or < ; then use logic to decide where (which side of the line) the possible solutions exist. Example: for x>2, Plot an x=2 vertial line. The solutions are on the right side of that line. The x<2 area could be "shaded" somehow to show that solutions cannot exist there.

When dealing with more than one inequality, plot all of the lines in this way to decide what (x,y) combinations are allowed

C/2 + C/2= 1/2

Add the two C/2's together and see what you get.

12.4=5*b/2

5-5
