Solution

Para resolver el sistema de ecuaciones, sigamos estos pasos:

  1. Tenemos el sistema de ecuaciones: {x3y=52x+y=10 \begin{cases} x - 3y = 5 \\ 2x + y = 10 \end{cases}

  2. Primero, despejamos y y de la segunda ecuación: 2x+y=10    y=102x 2x + y = 10 \implies y = 10 - 2x

  3. Sustituimos y y en la primera ecuación: x3(102x)=5 x - 3(10 - 2x) = 5

  4. Simplificamos la ecuación: x30+6x=5    7x30=5 x - 30 + 6x = 5 \implies 7x - 30 = 5

  5. Despejamos x x : 7x=35    x=5 7x = 35 \implies x = 5

  6. Sustituimos x=5 x = 5 en la ecuación y=102x y = 10 - 2x : y=102(5)    y=0 y = 10 - 2(5) \implies y = 0

Por lo tanto, la solución del sistema de ecuaciones es (5,0) (5, 0) .
