$y^2=-\left(x^2+9\right)$
Learn how to solve equations problems step by step online. Solve the equation x^2+y^2+9=0. We need to isolate the dependent variable y, we can do that by simultaneously subtracting x^2+9 from both sides of the equation. Simplify the product -(x^2+9). Removing the variable's exponent. Cancel exponents 2 and 1.
