What is the inverse function of f(x)= 2x/3x-4

I need help with this i need the inverse function please!!

Presentation is incorrect and can but guess that what is meant is :-
f (x) = 2x / ( 3x - 4)

Let f (x) = y and g (y) = x
ie g is inverse of f

2x = y (3x - 4)
2x = 3yx - 4y
4y = (3y - 2) x
x = 4y / (3y - 2)
g (y) = 4y / (3y - 2)
g (x) = 4x / (3x - 2) <---------inverse function
