If
x+y=-4
y-3x=16 or we cn write as
x+y=-4
-3x+y=16
i multiply the first equation by 3
3x+3y=-12
-3x+ y=16
4y=4
y=1
x+1=-4
x=-5
Check the picture below. So,the parabola looks like so, notice the distance "p". since the parabola is opening to the right, then "p" is positive, thus is 5.

Answer:
x = -1
Step-by-step explanation:
5x + 5 = 0
Subtract 5 from each side
5x+5-5 = 0-5
5x = -5
Divide by 5 on each side
5x/5 = -5/5
x = -1
