1. Definimos la masa del salmón como m.
2. La mitad de la masa del salmón se representa como \frac{m}{2}.
3. Si a la mitad de la masa del salmón se le agregan 2 kg, se tiene \frac{m}{2} + 2.
4. El triple de un cuarto de la masa se representa como 3 \left( \frac{m}{4} \right).
5. Igualamos ambas expresiones según el problema:
\frac{m}{2} + 2 = 3 \left( \frac{m}{4} \right)

6. Resolvemos la ecuación:
\frac{m}{2} + 2 = \frac{3m}{4}

7. Para eliminar los denominadores, multiplicamos ambos lados de la ecuación por 4:
4 \left( \frac{m}{2} + 2 \right) = 4 \left( \frac{3m}{4} \right)

8. Esto simplifica a:
2m + 8 = 3m

9. Restamos 2m de ambos lados para resolver para m:
8 = m

10. La masa del salmón es:
m = 8 \, \text{kg}
