Can you show me the steps to solve for x?

if f(x) = c (a constant) then

c = 2ln(x-3)

Divide both sides by 2

(c/2) = ln(x-3)

Raise both sides to the power e

e^c/2 = e ^ln(x-3)

But, e^ln(a) = a so

e^c/2 = x-3

Add 3 to both sides

x = 3 + e^c/2 

.

To solve for x, you need to know the value of f(x).
