The system of linear equations - 2x + y = 8 and - 3x - y = 7 is graphed below?

The system of linear equations - 2x + y = 8 and - 3x - y = 7 is graphed below. What is the solution to the system of equations? A. (–3, 2) B. (–2, 3) C. (2, –3) D. (3, 2).

En resumen

Anabella - 2x + y = 8 (1) - 3x - y = 7 (2) Sumando (1) + ( 2) - 5x = 15 x = 15 / ( - 5) x = - 3 X en (1) [si prefieres, puedes usar (2)] - 2( - 3) + y = 8 6 + y = 8 y = 8 - 6 y = 2 Alternativa A.

Anabella - 2x + y = 8 (1) - 3x - y = 7 (2)

Sumando (1) + ( 2) - 5x = 15 x = 15 / ( - 5) x = - 3

X en (1) [si prefieres, puedes usar (2)] - 2( - 3) + y = 8 6 + y = 8 y = 8 - 6 y = 2 Alternativa A.
