It has been awhile since I worked with in qualities but I got the answer, -1/3 < or equal to p < or equal to 2. I multiplied the 5 in the middle of the equation with what's in parentheses to get 15p - 10, then I added 10 to both outer sides of the equation and got -5 < or equal to 15p < or equal to 30. Then lastly I divided 15 by -5 and 30! I hope that's right.. I'm sorry if it isn't!
