Solution for ln(x+1)+ln(x+5)=ln(13) equation: 


Simplifying
ln(x + 1) + ln(x + 5) = ln(13)

Reorder the terms:
ln(1 + x) + ln(x + 5) = ln(13)
(1 * ln + x * ln) + ln(x + 5) = ln(13)
(1ln + lnx) + ln(x + 5) = ln(13)

Reorder the terms:
1ln + lnx + ln(5 + x) = ln(13)
1ln + lnx + (5 * ln + x * ln) = ln(13)
1ln + lnx + (5ln + lnx) = ln(13)

Reorder the terms:
1ln + 5ln + lnx + lnx = ln(13)

Combine like terms: 1ln + 5ln = 6ln
6ln + lnx + lnx = ln(13)

Combine like terms: lnx + lnx = 2lnx
6ln + 2lnx = ln(13)

Reorder the terms for easier multiplication:
6ln + 2lnx = 13ln

Solving
6ln + 2lnx = 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.
6ln + -13ln + 2lnx = 13ln + -13ln

Combine like terms: 6ln + -13ln = -7ln
-7ln + 2lnx = 13ln + -13ln

Combine like terms: 13ln + -13ln = 0
-7ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-7 + 2x) = 0


Subproblem 1
Set the factor 'ln' equal to zero and attempt to solve:

Simplifying
ln = 0

Solving
ln = 0
