I have the problem halfway solved
posted by Nik .
9/7x + 8 < 4x  5
9/7x + 4x + 8 , 4x + 4x  5
9/7x + 4x +8 < 5
The book then has
19/7x + 8 <  5
I know how to solve this but I am lacking or trying to remeber how they got 19/7  need a refresher
Convert the "x" terms to common denominators
4 x  (9/7) x = 28 x  (9/7) x
= (19/7) x
