color(red)(y=-8

#### Explanation:

So, this is what you are starting with.

sqrt(y+color(red)(9))=color(red)(1

The first step to solving a radical equation is to get red of the square root. (So square both sides).

(y+color(red)(9))=color(red)(1^2
Then simplify.
(y+color(red)(9))=color(red)(1

$\textcolor{red}{y = 1 - 9}$

color(red)(y = -8#
