always get the absolute value part alone on 1 side first
|9-8x| = (2x+3)/9
then split it into 2 cases, pos and neg
--> 9-8x = (2x+3)/9
and
--> 9-8x = -(2x+3)/9
solve each equation for x

|9-8x| -> (9-8x) and (8x-9)
9 (9 - 8x) = 2x + 3
81 - 72x = 2x + 3
78 = 74x
x = 78/74 = 39/37
9 (8x - 9) = 2x + 3
72x - 81 = 2x + 3
70x = 84
x = 84/70 = 6/5
