Příklady z matematiky

                    x + 4y = 37  / (-2)

             2x + 5y = 53

             -2x – 8y = -74

              2x + 5y = 53

                     -3y = -21

                         y = 7

 

x = 37 – 4y = 37 – 4.7 = 9

 

L1 = 9 + 4.7 = 37 

P1 = 37

 

L2 = 2.9 + 5.7 = 53

P2= 53

 

                                 P = [9 ; 7]
