Question Regarding Linear Programming

Hi Tutor,

I already watched your video on the topic, but still confuse regarding couple of things. First that I am very good with the equation solution, but didn’t get the graph (or simply just don’t want to do it) is there any possibilities that I leave the graph and do the solution with the equation, do i need to make graph in the exam? I tried few questions in the BBP kit and it seems that doing graph way is mandatory, can you please confirm me? I would be great If I can leave graph sort of solution and do directly with the equation.
I hope I have clear the point, thanks sir in advance for your great efforts!
