How do you solve Ln 5 - Ln x = 3

I'm doing my math homework and I can't understand the example in the book. If you can help me I very much appreciate it. Thank you.

Simplifies to....

ln(5/x) = 3

5/x = e^3

x = 5e^(-3)

Property of logs : ln(a) - ln(b) = ln(a/b)

The inverse of e^x is ln(x) so ln(e^x) = x.

Ln(5/x) = 3
e^ln(5/x) = e^3
5/x = e^3

x = 5/e^3
