y-x=-6

Answer 1

Please help I really need to get this done!! PLEASE

Answer 2

Nm dont worry about this one... figured it out.. i might ahve a new question shortley

Answer 3

x^2+y^2=21
x^2-y=9

Answer 4

square the second equation,
x^2+y^2+2xy=36.
26+2xy=36
xy=5
x=5/y
y-5/y+6=0
y^2+6y-5=0 .

Answer 5

I woudl be really thankful if you can do that one i ust sent
x^2+y^2=21
x^2-y=9

Answer 6

9+y+y^2=21
y^2+y-12=0;
y=-4,y=3
then find x.

Answer 7

how?? i suck at these

Answer 8

can you tell me x plz?

Answer 9

if y=3,x=sqrt(12)
if y=-4,x=sqrt(5).
