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


Simplifying
ln(x + 2) + -1ln(2x) = ln(3)

Reorder the terms:
ln(2 + x) + -1ln(2x) = ln(3)
(2 * ln + x * ln) + -1ln(2x) = ln(3)
(2ln + lnx) + -1ln(2x) = ln(3)

Remove parenthesis around (2x)
2ln + lnx + -1ln * 2x = ln(3)

Reorder the terms for easier multiplication:
2ln + lnx + -1 * 2ln * x = ln(3)

Multiply -1 * 2
2ln + lnx + -2ln * x = ln(3)

Multiply ln * x
2ln + lnx + -2lnx = ln(3)

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

Reorder the terms for easier multiplication:
2ln + -1lnx = 3ln

Solving
2ln + -1lnx = 3ln

Solving for variable 'l'.

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

Add '-3ln' to each side of the equation.
2ln + -3ln + -1lnx = 3ln + -3ln

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

Combine like terms: 3ln + -3ln = 0
-1ln + -1lnx = 0

Factor out the Greatest Common Factor (GCF), '-1ln'.
-1ln(1 + x) = 0

Ignore the factor -1.

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.
