Explain solution RD Sharma class 12 chapter Linear Programming exercise 29.2 question 20 maths
Answer: the feasible region of the given LPP does not exist
Hint: plot the points on the graph
Given:
Solution: first we will convert the equations into equations, we obtain the following equation
Region represented by the : the line meets the coordinates axes A(-1, 0) and B(0, 1) respectively. By joining these points we obtain the line
Clearly (0, 0) does not satisfy the equation . So the region is the plane which does not contain the origin represents the solution set of the equation .
Region represented by . The line is the line passing through (0, 0). The region to the right of the line will satisfy the given equation . . if
we take a point (1, 3) to the left of the line . Here which is not satisfy the equation . therefore , the region to the right of the line will satisfy the given inequalition
Region represented by : since every point is the first quadrant is the region represented by the equations
The feasible region determined by the system of constraints
We observe that the feasible region of the given LPP does not exist
