Question

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

Answer 1

See explanation.

Explanation:

Divide out a `3`.

`(3n)/3 < 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`.
