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)
Y=1 and x=2 because 2+1=3 and 2(x) plus 3(y) is 5

Answer:
steps 3 went wrong
Step-by-step explanation:
the quadratic is
(-b +/- √ ( b^2 - 4ac) )/2a
-52 + √( 2704 +2772) /-14
-52 +74) / -14 = -22/14 = -11/7
-52 -74 / -14 = -126/-14 = 9
