For this case we must solve the given equation, for this we follow the steps below:

\sqrt {x-5} + 7 = 9

Step 1:

We subtract 7 from both sides of the equation:

\sqrt {x-5} + 7-7 = 9-7\\\sqrt {x-5} = 9-7\\\sqrt {x-5} = 2

Step 2:

We raise both sides of the equation to the square:

{(\sqrt {x-5})} ^ 2 = 2 ^ 2\\{(\sqrt {x-5})} ^ 2 = 4

By definition, we know that:{(\sqrt {x})} ^ 2 = x, so we have:

x-5 = 4

Step 3:

We add 5 to both sides of the equation:

x-5 + 5 = 4 + 5\\x = 9

Answer:

The value of x is 9.
