Which values for A and B will create infinitely many solutions for this system of equations?

4 x minus A y = 15. Negative 4 x + 6 y = B.

A) A = -6, B = 15
B) A = 6, B = 15
C) A = 6, B = -15
D) A = -6, B = -15

Respuesta :

TREKKER

Answer:

(C)

Step-by-step explanation:

4x - Ay = 15

-4x + 6y = B --> 4x - 6y = -B = 4x - Ay = 15

-B = 15; -6 = -A -->

B = -15; A = 6 (C)
