Question3. x+y=8x+2y=7\begin{aligned} x+y & =8 \\ -x+2 y & =7\end{aligned}

Studdy Solution
Verificamos la solución sustituyendo x=3 x = 3 y y=5 y = 5 en las ecuaciones originales:
Primera ecuación: x+y=8 x + y = 8
3+5=8 3 + 5 = 8
Segunda ecuación: x+2y=7 -x + 2y = 7
3+2(5)=7 -3 + 2(5) = 7
Ambas ecuaciones son verdaderas, por lo tanto, la solución es:
(x,y)=(3,5) (x, y) = (3, 5)
