Solution for ln(x+1)-ln(x-1)=ln(3x) equation:


Simplifying
ln(x + 1) + -1ln(x + -1) = ln(3x)

Reorder the terms:
ln(1 + x) + -1ln(x + -1) = ln(3x)
(1 * ln + x * ln) + -1ln(x + -1) = ln(3x)
(1ln + lnx) + -1ln(x + -1) = ln(3x)

Reorder the terms:
1ln + lnx + -1ln(-1 + x) = ln(3x)
1ln + lnx + (-1 * -1ln + x * -1ln) = ln(3x)
1ln + lnx + (1ln + -1lnx) = ln(3x)

Reorder the terms:
1ln + 1ln + lnx + -1lnx = ln(3x)

Combine like terms: 1ln + 1ln = 2ln
2ln + lnx + -1lnx = ln(3x)

Combine like terms: lnx + -1lnx = 0
2ln + 0 = ln(3x)
2ln = ln(3x)

Remove parenthesis around (3x)
2ln = ln * 3x

Reorder the terms for easier multiplication:
2ln = 3ln * x

Multiply ln * x
2ln = 3lnx

Solving
2ln = 3lnx

Solving for variable 'l'.

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

Add '-3lnx' to each side of the equation.
2ln + -3lnx = 3lnx + -3lnx

Combine like terms: 3lnx + -3lnx = 0
2ln + -3lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(2 + -3x) = 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

Set the factor '(2 + -3x)' equal to zero and attempt to solve: Simplifying 2 + -3x = 0 Solving 2 + -3x = 0 Move all terms containing l to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -3x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -3x = 0 + -2 -3x = 0 + -2 Combine like terms: 0 + -2 = -2 -3x = -2 Add '3x' to each side of the equation. -3x + 3x = -2 + 3x Combine like terms: -3x + 3x = 0 0 = -2 + 3x Simplifying 0 = -2 + 3x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
