Respuesta:
cada pieza de aguacates cuesta 5 pesos y cada pieza de tomate cuesta 7 pesos
Explicación paso a paso:
aguacate = a
tomate = t
3a + 5t = 50
5a + 7t = 74
3a = 50 - 5t
a = 50/3 - 5t/3
5 * (50/3 - 5t/3) + 7t = 74
250/3 - 25t/3 + 7t = 74
-4t/3 = 74 - 250/3
-4t/3 = -28/3
t = -28/3 / (-4/3)
t = 7
a = 50/3 - (5 * 7)/3
a = 50/3 - 35/3
a = 5
