Answer 2

Answer:

x=12

Step-by-step explanation:

To solve for the variable, we must isolate the variable, which is x.

$\sqrt{x+4} -3=1$

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.

$\sqrt{x+4} -3+3=1+3$

$\sqrt{x+4} =1+3$

$\sqrt{x+4} =4$

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

$(\sqrt{x+4})^2 =4^2$

$x+4=4^2$

Evaluate the exponent.

4^2= 4*4=16

$x+4=16$

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

$x+4-4=16-4$

$x=16-4$

$x=12$

The solution to this equation is x=12.
