Solution for ln(3x+5)=ln(12-6x) equation:


Simplifying
ln(3x + 5) = ln(12 + -6x)

Reorder the terms:
ln(5 + 3x) = ln(12 + -6x)
(5 * ln + 3x * ln) = ln(12 + -6x)
(5ln + 3lnx) = ln(12 + -6x)
5ln + 3lnx = (12 * ln + -6x * ln)
5ln + 3lnx = (12ln + -6lnx)

Solving
5ln + 3lnx = 12ln + -6lnx

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.
5ln + -12ln + 3lnx = 12ln + -12ln + -6lnx

Combine like terms: 5ln + -12ln = -7ln
-7ln + 3lnx = 12ln + -12ln + -6lnx

Combine like terms: 12ln + -12ln = 0
-7ln + 3lnx = 0 + -6lnx
-7ln + 3lnx = -6lnx

Add '6lnx' to each side of the equation.
-7ln + 3lnx + 6lnx = -6lnx + 6lnx

Combine like terms: 3lnx + 6lnx = 9lnx
-7ln + 9lnx = -6lnx + 6lnx

Combine like terms: -6lnx + 6lnx = 0
-7ln + 9lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-7 + 9x) = 0

Subproblem 1

Set the factor 'ln' equal to zero and attempt to solve: Simplifying ln = 0 Solving ln = 0 Move all terms containing l to the left, all other terms to the right. Simplifying ln = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2
