Answer
Solution set:
$x \lt 5$
Refer to the image below for the graph below.
Work Step by Step
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)
