-3+%3E+7y-3+%3E+-24 Start with the given compound inequality


-24+%3C+7y-3+%3C+-3 Reverse the compound inequality by switching the outer sides and reversing the inequality signs



-21%3C7y%3C0 Add 3 to all sides






-3%3Cy%3C0 Divide every side by 7 to isolate y.



So the solution in interval notation is: (-3,0)


Now let's graph the solution set



Note: at y=-3 there is a open circle (which means this point is excluded) and at y=0 there is a open circle (which means this point is excluded)
