# How do you find the constraints in a linear programming problem?

Dec 15, 2017

$\text{See explanation below}$

#### Explanation:

$\text{Well, you must read the text well and identify three things : }$
$\text{1) The linear function that has to be maximized/minimized}$
$\text{2) The variables, those occur in the linear function of 1)}$
$\text{3) The constraints are also a linear function of the variables,}$
$\text{and that function has to be ">=" or "<=" a number.}$

$\text{Sometimes there is a constraint =, but then we can eliminate}$
$\text{a variable by solving for that variable and substituting in the }$
$\text{other functions.}$
