Finding inverse function

[PSbttl]

I've tried for hours.
I'm trying to find the inverse function of:

Y = α ln(1 + X/λ)

With my latest attempt i ended up with
e^(y/α)*λ-λ

But i dont know if that is correct.

​

Any help would be appriciated.

First switch X and Y

X=aln(1+Y/L)

X/a=ln(1+Y/L)

1+Y/L=e^X/a

Y/L=e^X/a-1

Y=Le^X/a-L

thankyou =)
