we know that
The "feasible region" has vertices
The objective function is
To determine the minimum value of the objective function, substitute the value of x and the value of y of each vertex in the objective function and then compare the values
1) For (4,5)
x=4,y=5
2) For (4,6)
x=4,y=6
3) For (7,4)
x=7,y=4
4) For (3,6)
x=3,y=6
therefore
The minimum value is 24
