                  4x + 3y = 6

               2x +  y = 4    / (-3)

              4x + 3y = 6

             -6x – 3y = -12

                     -2x = -6

                        x = 3

 

 y =                = -2

 

 

L1= 3(-2) + 4 3 = 6

P1 = 6

 

L2 = 2 3 +(-2) = 4

P2 = 4

 

                                        P = [3, -2]
