Solution for ln(x+5)+ln(x-1)=0 equation:


Simplifying
ln(x + 5) + ln(x + -1) = 0

Reorder the terms:
ln(5 + x) + ln(x + -1) = 0
(5 * ln + x * ln) + ln(x + -1) = 0
(5ln + lnx) + ln(x + -1) = 0

Reorder the terms:
5ln + lnx + ln(-1 + x) = 0
5ln + lnx + (-1 * ln + x * ln) = 0
5ln + lnx + (-1ln + lnx) = 0

Reorder the terms:
5ln + -1ln + lnx + lnx = 0

Combine like terms: 5ln + -1ln = 4ln
4ln + lnx + lnx = 0

Combine like terms: lnx + lnx = 2lnx
4ln + 2lnx = 0

Solving
4ln + 2lnx = 0

Solving for variable 'l'.

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

Factor out the Greatest Common Factor (GCF), '2ln'.
