## Introductory Algebra for College Students (7th Edition)

Solution set: $x \lt 5$ Refer to the image below for the graph below.
Subtract 1 on both sides of the inequality to obtain: $x \lt 6-5 \\x \lt 5$ The numbers that are less than $7$ on a number line are the ones to the left of $5$. Thus, to graph the solution set on a number line, plot a hole (or hollow dot) at $x=57$ and shade the region to its left. (refer to the attached image in the answer part above)
