# How do you solve and graph  3n < 9 ?

See explanation.

#### Explanation:

Divide out a $3$.

$\frac{3 n}{3} < \frac{9}{3}$

$n < 3$

Now we solved for $n$. We need to graph it. On a number line, l find $3$. Put an open circle there. An open circle marks a boundary or all numbers up to that point, but not including that point. Then draw a line going left. This graph represents that $n < 3$ if $n$ is all values less than $3$.
