Sir can u explain question 2 how u find these critical points.....6x-y=4.......(1) -x+4y=7....(2)

[@npateaching5804]

As you already have system of linear equation (Simultaneous equation) with two unknowns (x, y), solve this equation to get critical values. You can understand how to solve this equation by using following following video: kzbin.info/www/bejne/oWioYXyepZelaNE or contact me on 9446909545
