Solution for ln(x+6)+ln(x-6)=ln(7) equation: 


Simplifying
ln(x + 6) + ln(x + -6) = ln(7)

Reorder the terms:
ln(6 + x) + ln(x + -6) = ln(7)
(6 * ln + x * ln) + ln(x + -6) = ln(7)
(6ln + lnx) + ln(x + -6) = ln(7)

Reorder the terms:
6ln + lnx + ln(-6 + x) = ln(7)
6ln + lnx + (-6 * ln + x * ln) = ln(7)
6ln + lnx + (-6ln + lnx) = ln(7)

Reorder the terms:
6ln + -6ln + lnx + lnx = ln(7)

Combine like terms: 6ln + -6ln = 0
0 + lnx + lnx = ln(7)
lnx + lnx = ln(7)

Combine like terms: lnx + lnx = 2lnx
2lnx = ln(7)

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

Solving
2lnx = 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.
-7ln + 2lnx = 7ln + -7ln

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