How do you solve and graph #-5<3p+7<=22#?
1 Answer
Explanation:
Remember that you can add or subtract any amount to all components of an inequality without changing the validity or orientation of the inequality.
Therefore
after subtracting
Also remember that you can multiply or divide all components of an inequality by any constant greater than zero without changing the validity or orientation of the inequality.
Therefore
after dividing all components by
Note that in drawing the number line graph for this solution, an open circle is used at
and a closed (or solid) circle is used at
