Which of the following are feasible solutions for a linear programming problem with constraints
x ≥0, y ≥ 0
3x+5y ≤ 15
5x+2y ≤ 10
In the last session we saw feasible region formed by the constraints of a linear programming problem. Feasible solution is any point in the feasible region.
We can also say a feasible solution is the values of decision variables( x and y) which satisfy the constraints given to us.
We will go through each option and see which among them satisfy our conditions x ≥ 0,y ≥ 0
3x+5y ≤ 15, 5x+2y ≤ 10.
The points (1,-1) and (-3, 5) clearly does not satisfy the constraints because we want both the coordinates to be non negative as x ≥ 0, y ≥ 0 are two constraints.
(0,0) and (2,0) satisfy all the conditions given.
