Step-by-step explanation:
first take an inequality .remove the inequality sign and then draw its graph .
now put the value x=y=0 in the inequality equation to check if its within the graph .if it satisfies the eqn then shade that part of the line which has the origin in it .similarly do for other inequalities.
you will/may get a polygon .it may be bounded or not. now by fundamental theory of lpp, obtain the terminal points
and get the values of x and y. calculate the respective value of fx and find the maximum and minimum of them .the answer will be the respective x and y values.
