Work Step by Step
$ x-3\leq-5\qquad$ ...add $3$ to each side of the inequality. $ x-3+3\leq-5+3\qquad$ ...simplify. $x\leq-2$ The solutions of the given inequality are all real numbers less or equal to $-2$.. Smaller numbers are to the left of $-2$. Use a solid dot in the graph to indicate $-2$ is a solution.
