2%3Cx%2B6%3C9 Start with the given inequality





-4%3Cx%3C3 Subtract 6 from all sides




So the solution in interval notation is: (-4,3)


Now let's graph the solution set



Note: at x=-4 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)
