Solution for ln(4x-1)=ln(3x+5) equation:


Simplifying
ln(4x + -1) = ln(3x + 5)

Reorder the terms:
ln(-1 + 4x) = ln(3x + 5)
(-1 * ln + 4x * ln) = ln(3x + 5)
(-1ln + 4lnx) = ln(3x + 5)

Reorder the terms:
-1ln + 4lnx = ln(5 + 3x)
-1ln + 4lnx = (5 * ln + 3x * ln)
-1ln + 4lnx = (5ln + 3lnx)

Solving
-1ln + 4lnx = 5ln + 3lnx

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.
-1ln + -5ln + 4lnx = 5ln + -5ln + 3lnx

Combine like terms: -1ln + -5ln = -6ln
-6ln + 4lnx = 5ln + -5ln + 3lnx

Combine like terms: 5ln + -5ln = 0
-6ln + 4lnx = 0 + 3lnx
-6ln + 4lnx = 3lnx

Add '-3lnx' to each side of the equation.
-6ln + 4lnx + -3lnx = 3lnx + -3lnx

Combine like terms: 4lnx + -3lnx = 1lnx
-6ln + 1lnx = 3lnx + -3lnx

Combine like terms: 3lnx + -3lnx = 0
-6ln + 1lnx = 0

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