Solution for ln(x-2)=ln(7) equation: 


Simplifying
ln(x + -2) = ln(7)

Reorder the terms:
ln(-2 + x) = ln(7)
(-2 * ln + x * ln) = ln(7)
(-2ln + lnx) = ln(7)

Reorder the terms for easier multiplication:
-2ln + lnx = 7ln

Solving
-2ln + lnx = 7ln

Solving for variable 'l'.

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

Add '-7ln' to each side of the equation.
-2ln + -7ln + lnx = 7ln + -7ln

Combine like terms: -2ln + -7ln = -9ln
-9ln + lnx = 7ln + -7ln

Combine like terms: 7ln + -7ln = 0
-9ln + lnx = 0
