# How do you solve sqrt(x+2)=4?

Oct 9, 2015

$x = 14$

#### Explanation:

In order to solve this problem, we need to get rid of the square root on the left side. To do this, we square both sides:

$\sqrt{x + 2} = 4$
$x + 2 = 16$

From here we need to get the variable alone. To do this we need to subtract 2 from both sides.

$x + 2 = 16$
$x = 14$

We then come to our answer.
Hope this helped!

#### Explanation:

$\sqrt{X + 2} = 4$

Square both sides

${\left(\sqrt{\left(X + 2\right)}\right)}^{2} = {4}^{2}$

X +2 = 16

Rearrange equations by taking constant from left hand side to right hand side

X = 16-2 =
14
