See a solution process below:

Explanation:

First, subtract color(red)(1) from each side of the equation to isolate the radical while keeping the equation balanced:

sqrt(x) + 1 - color(red)(1) = 5 - color(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:

(sqrt(x))^2 = 4^2

x = 16
