tu mera koi na hoke bhi kuch laage🥰, awesome explanation

[delawarysingh]

sir you explain better than my class teacher Thankyou :)

[dollysingh]

You are super teacher for mathematics

Sir in last question value of z is
21 na how 35 sir at point B?

[dakshjainth]

sir it may be greatest at p because 7*3 = 21

[Jakhar-lqvy]

But Sir, in upsc they give to solve questions of 3 variables using graphical method
So, plz explain that also

[samikshamaurya]

Sir, in last case where the feasible region is in downward direction .why the feasible region is not restricted to first quadrant ..as the value of X1 and X2 is >0 .i.e the minimum can be obtained in one of those conrner points ...

Sir,
Can we use graphical method if all the constraints are Equality type with two variables?

[engineer]

If three vraiable, How we can solve it

[m]

What if we have a objective function with 3 variable can we do the same ?

Max Z= 3x1+2x2
S.t.c. x1 - x2>=1
x1+x3>=3
x1, x2, x3>=0
Solve by graphical method
Can u solve this
