Find the maximum value of the function for the polygonal convex set determined by the given system of inequalities

A. at (8,7) the maximum value is 98

Step-by-step explanation:

First draw the region, that is bounded by all inequalities. This is the triangle with vertices (6,1), (2,5) and (8,7).

Now you can see where the line f(x,y)=7x+6y intersect this region. The maximum value will be at endpoints of this region:

Thus, the maximum value of the function is 98 at the point (8,7).

too hard the other guy did it
