Termometría. Las temperaturas iniciales de m gramos del líquido A, 2m gramos del líquido B y 3m gramos del líquido C son respectivamente 30° C, 20°C y 10°C; mezclando los líquidos A y B la temperatura final es 25°C; mezclando los líquidos B y C, la temperatura final es 14,5°C. ¿Cuál será la temperatura final si se mezclan los líquidos A y C? Desprecia la capacidad calorífica del calorímetro y supóngase que no hay reacciones químicas durante la mezcla de líquidos.

Can someone explain to me how to do this problem ?
