Solution for ln(x+9)=ln(13) equation: 


Simplifying
ln(x + 9) = ln(13)

Reorder the terms:
ln(9 + x) = ln(13)
(9 * ln + x * ln) = ln(13)
(9ln + lnx) = ln(13)

Reorder the terms for easier multiplication:
9ln + lnx = 13ln

Solving
9ln + lnx = 13ln

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Add '-13ln' to each side of the equation.
9ln + -13ln + lnx = 13ln + -13ln

Combine like terms: 9ln + -13ln = -4ln
-4ln + lnx = 13ln + -13ln

Combine like terms: 13ln + -13ln = 0
-4ln + lnx = 0
