-14%3C7x%3C21 Start with the given inequality




-2%3Cx%3C3 Divide every side by 7 to isolate x.



So the solution in interval notation is: (-2,3)


Now let's graph the solution set



Note: at x=-2 there is a open circle (which means this point is excluded) and at x=3 there is a open circle (which means this point is excluded)
