Answer
$x\leq5$
Work Step by Step
$x+5\leq10\longrightarrow$ subtract 5 from each side
$x+5-5\leq10-5\longrightarrow$ subtract
$x\leq5$
Check the endpoint.
$5+5\overset?=10$
$10=10\checkmark$
Check the inequality.
$4+5\overset?\lt10$
$9\lt10\checkmark$
Since 5 is included in the solution, the endpoint of the graph is a solid circle.
