### Instruction: If $\sqrt{5+n}=7$, then what is the value of $n$?### Response: To solve for $n$, I need to isolate it on one side of the equation.
First, I can square both sides of the equation to get rid of the square root.
Squaring both sides gives me $5+n=49$.
Next, I can subtract $5$ from both sides to get $n=44$.
