I think that you should start by multipling both sides by your denominator. That will give you
(ax+b) > cb
then you subtract b from both sides
ax > cb - b
then you divide both sides by a and that yields
x > (cb - b)/a
you could even factor the b term in the numerator and get
x > b(c-1)/a

There is no C in the inequality you gave.
x>a+b/x

(ax+b)/c >b
(ax+b) > bc
ax > bc-b
x>(bc-b/a)
x>b(c-1)/a

(ax+b) / c > b
-(ax + b) / (-c) > b
-(ax+b) > -bc
-ax - b > -bc
-ax > b - bc
x > (b-bc)/(-a)
x > (bc-b)/a
