The minimum or maximum value of a quantity are what are used to maximize or minimize a function.
<em>The method for finding these minimum or maximum value is linear programming.</em>
<em />
Take for instance, the following parameters:

Subject to:



The above is an illustration of a linear programming.
It is useful in the following areas:
- To formulate real life problems
- To get an optimal solution
- To maximize profit and minimize cost
- Etc

It is given that
a+b=20 -------------------- (1)
b+c=30 -----------------------(2)
We have to calculate
3 a + 4 b +7 c
Now multiplying equation(1 )by 3,we get
3 a+ 3 b=60 ----------------------------------(3)
and Multiplying equation( 2) by 4,we get
4 b + 4 c=120 -----------------------------------(4)
Adding expression (3) and (4),we get i.e left hand side of 3 to left hand side of 4 and right hand side of 3 to right hand side of 4.
3 a+ 3 b+ 4 b+ 4 c=60+120
Adding like terms, we get
3 a+ 7 b+ 4 c =180, Which is the required solution.
