Question

question solve the system by substitution. y = -5x y = -7x - 14 answer attempt 1 out of 2 (\boxed{}, \boxed{}) submit answer

Explanation:

Step1: Sustituir \( y = -5x \) en \( y = -7x - 14 \)

Sustituimos la primera ecuación en la segunda para encontrar \( x \):
\( -5x = -7x - 14 \)

Step2: Resolver para \( x \)

Sumamos \( 7x \) a ambos lados:
\( -5x + 7x = -14 \)
\( 2x = -14 \)
Dividimos por 2:
\( x = \frac{-14}{2} = -7 \)

Step3: Encontrar \( y \) usando \( y = -5x \)

Sustituimos \( x = -7 \) en \( y = -5x \):
\( y = -5(-7) = 35 \)

Answer:

\((-7, 35)\)
