Hi, I think for part ii) your answer is incorrect. It shouldn't be 5/3 < x < 7. When x = 5/3, the entire expression equates to 0, so anything more than 5/3 will cause the solution to be bigger than 0. However the question is asking for answers less than 0. So it should be anything that is less than 5/3. The answer should be x<5/3 instead?
