In this problem, they have given that the objective function of the lpp minimizes the result which is equal to 3x plus 2y and subject to the constraints x plus y which is less than or equal to 12 and 2x plus 2y which is greater than or equal to 4, x comma y greater than or equal to 0.

We need to solve this lpp using the graphical method.
00:27
For drawing the graph, first i take x plus y which is equal to 1, then x, y, x equal to 0, then y equal to 12, x equal to 12, y equal to 0 and 2x plus 2y which is equal to 4, which implies x plus y which is equal to 2, then x, y, x equal to 0, y equal to 2, x equal to 2, y equal to 0.

Therefore, the graph for the given lpp is this is 0 comma 12 and this one is 12 comma 0, this is 9 and this is 0 comma 2 and this is 2 comma 0, this is 0 comma 0, this curve is x plus y which is less than or equal to 12 and this curve is 2x plus 2y which is greater than or equal to 4.
