Solution for 2ln(x+1)=ln(8-4x) equation:


Simplifying
2ln(x + 1) = ln(8 + -4x)

Reorder the terms:
2ln(1 + x) = ln(8 + -4x)
(1 * 2ln + x * 2ln) = ln(8 + -4x)
(2ln + 2lnx) = ln(8 + -4x)
2ln + 2lnx = (8 * ln + -4x * ln)
2ln + 2lnx = (8ln + -4lnx)

Solving
2ln + 2lnx = 8ln + -4lnx

Solving for variable 'l'.

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

Add '-8ln' to each side of the equation.
2ln + -8ln + 2lnx = 8ln + -8ln + -4lnx

Combine like terms: 2ln + -8ln = -6ln
-6ln + 2lnx = 8ln + -8ln + -4lnx

Combine like terms: 8ln + -8ln = 0
-6ln + 2lnx = 0 + -4lnx
-6ln + 2lnx = -4lnx

Add '4lnx' to each side of the equation.
-6ln + 2lnx + 4lnx = -4lnx + 4lnx

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

Combine like terms: -4lnx + 4lnx = 0
-6ln + 6lnx = 0

Factor out the Greatest Common Factor (GCF), '6ln'.
6ln(-1 + x) = 0

Ignore the factor 6.

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.
