x=12
Step-by-step explanation:
To solve for the variable, we must isolate the variable, which is x.

3 is being subtracted from the square root of x+4. The inverse of subtraction is addition. Add 3 to both sides of the equation.



The square root of x+4 is being taken. The inverse of a square root is a square. Square both sides of the equation.


Evaluate the exponent.
4^2= 4*4=16

4 is being added to x. The inverse of addition is subtraction. Subtract 4 from both sides of the equation.



The solution to this equation is x=12.
