How to solve for $x$ : $ae^{bx}+x = c$
I've tried to solve it with the Lambert W function, but, in all of the methods I tried, I had $x$ as the Lambert W function parameter. Can I solve it without graphs? Thank you for your help.

$$ae^{bx}+x=c$$
$$ae^{bx}=c-x$$
$$ae^{bc-b(c-x)}=c-x$$
$$abe^{bc}=b(c-x)e^{b(c-x)}$$
$$b(c-x)=W(abe^{bc}).$$
$$x=c-\frac1bW(abe^{bc}).$$
(By hand.)
