LINCON   l_con [ , l_con …]   ; 
            
where l_con is given in one of the following formats:
linear_term operator number
number operator linear_term
and linear_term is of the following form:
| ![\[  <+|-> < \mr {number *} > \mr {variable} <+|- < \mr {number *} > \mr {variable} \ldots >  \]](images/ormplpug_nlp0189.png) | 
 The value of operator can be one of the following:  or
 or  .
. 
         
The LINCON statement specifies equality or inequality constraints
| ![\[  \sum _{j=1}^ n a_{ij} x_ j \:  \{ \le | = | \ge \}  \:  b_ i \quad \mr {for} \;  i=1,\ldots ,m  \]](images/ormplpug_nlp0032.png) | 
 separated by commas. For example, the constraint  is expressed as
 is expressed as 
         
decvar x1 x2; lincon 4 * x1 - 3 * x2 = 0;
and the constraints
| ![\[  10x_1 - x_2 \geq 10  \]](images/ormplpug_nlp0191.png) | 
| ![\[  x_1 + 5x_2 \geq 15  \]](images/ormplpug_nlp0192.png) | 
are expressed as
   decvar x1 x2;
   lincon 10 <= 10 * x1 - x2,
          x1 + 5 * x2 >= 15;
