Si se compran tres chicles y un tamarindo y se paga $15 y se compran dos chicles y tres tamarindos y se paga $31 ¿que cuesta cad
a tamarindo?
1 answer:
Responder:
9
Explicación paso a paso:
Dejar :
Mascar chicle = x
Tamarindo = y
3x + y = 15 - - - (1)
2x + 3y = 31 - - - (2)
De 1)
y = 15 - 3x - - (3)
Por lo tanto,
2x + 3 (15 - 3x) = 31
2x + 45 - 9x = 31
-7x = 31 - 45
-7x = - 14
x = 2
De (3):
y = 15 - 3 (2)
y = 15 - 6
y = 9
