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


Simplifying
ln(x + 4) + -1ln(x + -2) = lnx

Reorder the terms:
ln(4 + x) + -1ln(x + -2) = lnx
(4 * ln + x * ln) + -1ln(x + -2) = lnx
(4ln + lnx) + -1ln(x + -2) = lnx

Reorder the terms:
4ln + lnx + -1ln(-2 + x) = lnx
4ln + lnx + (-2 * -1ln + x * -1ln) = lnx
4ln + lnx + (2ln + -1lnx) = lnx

Reorder the terms:
4ln + 2ln + lnx + -1lnx = lnx

Combine like terms: 4ln + 2ln = 6ln
6ln + lnx + -1lnx = lnx

Combine like terms: lnx + -1lnx = 0
6ln + 0 = lnx
6ln = lnx

Solving
6ln = lnx

Solving for variable 'l'.

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

Add '-1lnx' to each side of the equation.
6ln + -1lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
6ln + -1lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(6 + -1x) = 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 '(6 + -1x)' equal to zero and attempt to solve: Simplifying 6 + -1x = 0 Solving 6 + -1x = 0 Move all terms containing l to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + -1x = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -1x = 0 + -6 -1x = 0 + -6 Combine like terms: 0 + -6 = -6 -1x = -6 Add 'x' to each side of the equation. -1x + x = -6 + x Combine like terms: -1x + x = 0 0 = -6 + x Simplifying 0 = -6 + x 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.
