I have to find the inverse function of f(x)=34x. I got y=3x/4 for the function. I then have to plug it back into the function and verify that it is the inverse. So I wrote (34(3x))/4. This resulted in (3+x)/4=x. I tried isolating it to get x=x but I just can't get it. Where did I goof up?

if g(x) is the inverse of f(x), then
f(g(x)) should equal x.
You proved that....
f(inverse)=(34(3x))/4=x
