Question

solve the inequality and graph the solution. 1 > n - 3 plot the endpoints. select an endpoint to change it from closed to open. select the middle of the segment, ray, or line to delete it.

Explanation:

Step1: Isolate the variable n

Add 3 to both sides of the inequality $1>n - 3$.
$1+3>n-3 + 3$

Step2: Simplify the inequality

$4>n$, which can also be written as $n<4$.

Answer:

The solution of the inequality is $n<4$. On the number - line, an open circle is placed at 4 (since 4 is not included in the solution set) and the line extends to the left towards negative infinity.
