Question

How do you solve and graph `w - 1 < 4`?

Answer 1

See below:

Explanation:

We need to add `1` to both sides to get

`w<5`

To graph this on a number line, we need to make an open circle at `5`, because the domain doesn't include `5`. Since the domain is comprised of values less than `5`, we draw an arrow pointing to the left and continuing.

Hope this helps!
