x^2 + y^2 = 36 y = 6 - x^2 Can you help me please
6-y+y^2=36. => y^2 - y - 30 = 0 Factoring: (y-6)(y+5)=0 => y = 6 or -5. You can then plug in y = 6 or y = -5 into the original first equation to get your values of x. x^2 + (-5^2) = 36 => x^2 + 25 = 36 => x^2 = 11 => x = sqrt(11). x^2 + 6^2 = 36 => x^2 + 36 = 36 => x^2 = 0 => x = 0.
