X/2 + Y/3 = 4
[3X + 2Y]/6 = 4
3X + 2Y = 24;
X/3 + Y = 1
[X + 3Y]/3 = 1
X + 3Y = 3;
3X + 2Y = 24; 3X = 24 - 2Y; X = 8 - (2/3)Y
X + 3Y = 3; 8 - (2/3)Y + 3Y = 3
3Y - (2/3)Y = -5
9Y/3 - 2Y/3 = -5
7Y/3 = -5; 7Y = -15; Y = -15/7
X = 8 - (2/3)(-15/7) = 8 + 10/7 = 56/7 + 10/7 = 66/7
(66/7 , -15/7)
La solucion es X = 66/7; Y = -15/7
Te anexo la grafica
