Question

Slove the system using substitution,
x-3y=0
9x-y*y=0

There are two solutions (x1,y1) (x2,y2)

1. for x1< x2*x1 = ????

2. y1=?????

3. x2=?????

4. y2=?????

Answer 1

x=3y
27y-y^2=0
y(27-y)=0
y=0
y=27
x=0
x=81

Answer 2

(0,0) and (81,27)

Answer 3

Thanks so much!!! That makes sense :)
