Answer:

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#.
