ANSWER

The value of x is
16.


EXPLANATION

We want to solve the equation,


\sqrt{x + 9}  - 4 = 1

The first step is to add 4 to both sides of the equation to obtain,


\sqrt{x + 9}   = 1 + 4



We simplify the right hand side to obtain,


\sqrt{x + 9}  = 5



We now square both sides of the equation to obtain,



(\sqrt{x + 9}  ) ^{2}  =  {5}^{2}



This simplifies to


x + 9= 25



We solve for x to obtain,



x = 25 - 9


This implies that,


x = 16
