Ex6.3, 7 Solve the following system of inequalities graphically: 2x + y 8, x + 2y 10 First we solve 2x + y 8 Lets first draw graph of 2x + y = 8 Drawing graph Checking for (0,0) Putting x = 0, y = 0 2x + y 8 0 + 0 8 0 8 which is false . Hence origin does not lie in plane 2x + y 8 So, we shade right side of line First we solve x + 2y 10 Lets first draw graph of x + 2y = 10 Drawing graph Checking for (0,0) Putting x = 0, y = 0 x + 2y 10 2(0)+(0) 10 0 10 which is false .Hence origin does not lie in plane x + 2y 10 So, we shade right upper side of line Hence the shaded region is the solution of the given in equality
