#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#

#color(red)(y=1 - 9)#

#color(red)(y = -8#
