Solution for ln(x-2)-ln(x+2)=ln(x-1)-ln(2x+4) equation:


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

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

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

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

Combine like terms: -2ln + -2ln = -4ln
-4ln + lnx + -1lnx = ln(x + -1) + -1ln(2x + 4)

Combine like terms: lnx + -1lnx = 0
-4ln + 0 = ln(x + -1) + -1ln(2x + 4)
-4ln = ln(x + -1) + -1ln(2x + 4)

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

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

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

Combine like terms: -1ln + -4ln = -5ln
-4ln = -5ln + lnx + -2lnx

Combine like terms: lnx + -2lnx = -1lnx
-4ln = -5ln + -1lnx

Solving
-4ln = -5ln + -1lnx

Solving for variable 'l'.

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

Add '5ln' to each side of the equation.
-4ln + 5ln = -5ln + 5ln + -1lnx

Combine like terms: -4ln + 5ln = 1ln
1ln = -5ln + 5ln + -1lnx

Combine like terms: -5ln + 5ln = 0
1ln = 0 + -1lnx
1ln = -1lnx

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

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

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