Para encontrar los valores de x y y tal que:

x + y = 19
x - y = 17

Podemos resolver este sistema de ecuaciones sumando las dos ecuaciones para eliminar y :

(x + y) + (x - y) = 19 + 17
2x = 36
x = 18

Ahora, podemos sustituir x en una de las ecuaciones originales para encontrar y . Usando la primera ecuación:

18 + y = 19
y = 19 - 18
y = 1

Por lo tanto, los valores de x y y son:
x = 18
y = 1

\textbf{Respuesta:} x = 18, \quad y = 1
