Question

what is the solution to the system of linear equations?
$2x + 4y = 16$
$-2x + 5y = 20$
solution: ( , )

Explanation:

Step1: Sumar las ecuaciones

Sumamos las dos ecuaciones \(2x + 4y = 16\) y \(-2x + 5y = 20\) para eliminar \(x\).

$$ LATEXBLOCK0 $$

Step2: Resolver para \(y\)

Dividimos ambos lados de la ecuación \(9y = 36\) por 9:

$$ y=\frac{36}{9}=4 $$

Step3: Sustituir \(y\) en una ecuación

Sustituimos \(y = 4\) en la ecuación \(2x + 4y = 16\):

$$ LATEXBLOCK1 $$

Answer:

\((0, 4)\)
