Answer 1

Answer:

We draw the graphs of the lines x + 2y = 8 and 2x + y = 8 The inequality (1) and (2) represent the region below the two lines including the point on the respective lines

Since x≥0,y≥0 every point in the shaded region in the first quadrant represent a solution of the given system of inequalities
