Solution for ln(4)+ln(x-8)=ln(18) equation: 


Simplifying
ln(4) + ln(x + -8) = ln(18)

Reorder the terms for easier multiplication:
4ln + ln(x + -8) = ln(18)

Reorder the terms:
4ln + ln(-8 + x) = ln(18)
4ln + (-8 * ln + x * ln) = ln(18)
4ln + (-8ln + lnx) = ln(18)

Combine like terms: 4ln + -8ln = -4ln
-4ln + lnx = ln(18)

Reorder the terms for easier multiplication:
-4ln + lnx = 18ln

Solving
-4ln + lnx = 18ln

Solving for variable 'l'.

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

Add '-18ln' to each side of the equation.
-4ln + -18ln + lnx = 18ln + -18ln

Combine like terms: -4ln + -18ln = -22ln
-22ln + lnx = 18ln + -18ln

Combine like terms: 18ln + -18ln = 0
-22ln + lnx = 0
