Solution for ln(4x+3)=2ln(4x-3) equation:


Simplifying
ln(4x + 3) = 2ln(4x + -3)

Reorder the terms:
ln(3 + 4x) = 2ln(4x + -3)
(3 * ln + 4x * ln) = 2ln(4x + -3)
(3ln + 4lnx) = 2ln(4x + -3)

Reorder the terms:
3ln + 4lnx = 2ln(-3 + 4x)
3ln + 4lnx = (-3 * 2ln + 4x * 2ln)
3ln + 4lnx = (-6ln + 8lnx)

Solving
3ln + 4lnx = -6ln + 8lnx

Solving for variable 'l'.

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

Add '6ln' to each side of the equation.
3ln + 6ln + 4lnx = -6ln + 6ln + 8lnx

Combine like terms: 3ln + 6ln = 9ln
9ln + 4lnx = -6ln + 6ln + 8lnx

Combine like terms: -6ln + 6ln = 0
9ln + 4lnx = 0 + 8lnx
9ln + 4lnx = 8lnx

Add '-8lnx' to each side of the equation.
9ln + 4lnx + -8lnx = 8lnx + -8lnx

Combine like terms: 4lnx + -8lnx = -4lnx
9ln + -4lnx = 8lnx + -8lnx

Combine like terms: 8lnx + -8lnx = 0
9ln + -4lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(9 + -4x) = 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
