# How do you solve sqrt(x) + 1=5?

See a solution process below:

#### Explanation:

First, subtract $\textcolor{red}{1}$ from each side of the equation to isolate the radical while keeping the equation balanced:

$\sqrt{x} + 1 - \textcolor{red}{1} = 5 - \textcolor{red}{1}$

$\sqrt{x} + 0 = 4$

$\sqrt{x} = 4$

Now, square each side of the equation to solve for $x$ while keeping the equation balanced:

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

$x = 16$
