What is the solution of the system? Use substitution.

-4y - 3x = - 11

x-2y = 17

A. (-9,-4)

B. (9,4)

C. (9,-4)

D. (-9,4)

C) (x, y) = (9,-4)

Step-by-step explanation:

-4y - 3x = - 11

x-2y = 17

-4y - 3x = - 11

x = 17+2y

-4y - 3 (17+2y) = - 11

x = 17+2y

-4y-51-6y=-11

x = 17+2y

-10y=-11+51

x = 17+2y

-10y=40

x = 17+2y

y=40 / (-10)

x = 17+2y

y=-4

x = 17+2 (-4)

y=-4

x=17-8

y=-4

x=9

(x, y) = (9,-4)
