which ordered pair is a solution to the system?. {x+4y=19. {y=-2x-4. . a) (-5, 6). b) (-2, 0). c) (3, 4). d) (7,3)
jarptica [38.1K]

Apply substitution

x+4(-2x-4)=19

x – 8x – 16 = 19

-7x = 19 + 16

-7x = 35

x = -5

Then substitute this value to the other equation

y=-2x-4

y = -2(-5) – 4

y = 10 – 4

y = 6

the answer is then letter A. (-5,6)
