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


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

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

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

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

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

Solving
2lnx = 1ln + lnx

Solving for variable 'l'.

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

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

Combine like terms: 1ln + -1ln = 0
-1ln + 2lnx = 0 + lnx
-1ln + 2lnx = lnx

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

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

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