Question

Solve the system:

9x^2 + y^2=9
3x-y=3

Answer 1

first isolate one variable in one of the equations( the easiest)

3x-y = 3
-y=3-3x
y = -3 + 3x
then fill in y in the other equation:
9x^2 + (-3+3x)^2 = 9
9x^2 + 9 + 9x = 9
9x^2+9x = 0

Here is where I get stuck, but does what I have make any sense to you?

Answer 2

Ok I figured it out from here thanks!
