Answer:

See the entire solution process below:

Explanation:

First, square each side of the equation to eliminate the radical while keeping the equation balanced:

#(sqrt(x + 3))^2 = -5^2#

#x + 3 = 25#

Now, subtract #color(red)(3)# from each side of the equation to solve for #x#:

#x + 3 - color(red)(3) = 25 - color(red)(3)#

#x + 0 = 22#

#x = 22#
