Explanation:

Step1: Isolate the variable x

Subtract 7 from both sides of the inequality $9 < 7 + x$.
$9-7<7 + x-7$

Step2: Simplify the inequality

$2 < x$ which can also be written as $x>2$.

Answer:

Inequality Notation: $x > 2$
Number Line: An open - circle at 2 and a line extending to the right.
