Solution for ln(5x+6)=2ln(5x-6) equation:


Simplifying
ln(5x + 6) = 2ln(5x + -6)

Reorder the terms:
ln(6 + 5x) = 2ln(5x + -6)
(6 * ln + 5x * ln) = 2ln(5x + -6)
(6ln + 5lnx) = 2ln(5x + -6)

Reorder the terms:
6ln + 5lnx = 2ln(-6 + 5x)
6ln + 5lnx = (-6 * 2ln + 5x * 2ln)
6ln + 5lnx = (-12ln + 10lnx)

Solving
6ln + 5lnx = -12ln + 10lnx

Solving for variable 'l'.

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

Add '12ln' to each side of the equation.
6ln + 12ln + 5lnx = -12ln + 12ln + 10lnx

Combine like terms: 6ln + 12ln = 18ln
18ln + 5lnx = -12ln + 12ln + 10lnx

Combine like terms: -12ln + 12ln = 0
18ln + 5lnx = 0 + 10lnx
18ln + 5lnx = 10lnx

Add '-10lnx' to each side of the equation.
18ln + 5lnx + -10lnx = 10lnx + -10lnx

Combine like terms: 5lnx + -10lnx = -5lnx
18ln + -5lnx = 10lnx + -10lnx

Combine like terms: 10lnx + -10lnx = 0
18ln + -5lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(18 + -5x) = 0
