Consider the equations
color(white)("XXXXX")XXXXXx=2x=2 which is a vertical line through (2,0)(2,0)
color(white)("XXXXX")XXXXXcolor(white)("XXXXX")XXXXXx>=2x2 will be all points on this line plus all points to the right of it

color(white)("XXXXX")XXXXXy+x=5y+x=5 which is a line through the points (0,5) and (5,0)(0,5)and(5,0)
color(white)("XXXXX")XXXXXcolor(white)("XXXXX")XXXXXy+x<=5y+x5 will be all points on this line and all points below and to the left of it.

x>=2 and y+x<=5x2andy+x5 will be the intersection of these two areas
