    is it \(-4\sqrt{x+9}=20\) or is it \[-4\sqrt{x}+9=20\]?

    then there is no answer, because the left hand side \(-4\sqrt{x+9}\) is negative, but the right hand side \(20\) is positive

    \(\sqrt{a}\) is always greater than or equal to zero, so when you multiply by \(-4\) the term will be less than or equal to zero, and it cannot equal a positive number
