Work Step by Step
To solve z+7$\leq$9, isolate z. To do this, subtract 7 on each side of the inequality. It then becomes z$\leq$2. To graph, place a solid circle on 2 because the answer includes the value 2 (you also know to shade it because the inequality includes the "and" symbol along with the "less than" symbol). Then, shade left of the 2 because the other values for x are less than 2.
