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


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

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

Reorder the terms for easier multiplication:
-1ln + 4lnx = 5ln + -1ln(x + -5)

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

Combine like terms: 5ln + 5ln = 10ln
-1ln + 4lnx = 10ln + -1lnx

Solving
-1ln + 4lnx = 10ln + -1lnx

Solving for variable 'l'.

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

Add '-10ln' to each side of the equation.
-1ln + -10ln + 4lnx = 10ln + -10ln + -1lnx

Combine like terms: -1ln + -10ln = -11ln
-11ln + 4lnx = 10ln + -10ln + -1lnx

Combine like terms: 10ln + -10ln = 0
-11ln + 4lnx = 0 + -1lnx
-11ln + 4lnx = -1lnx

Add 'lnx' to each side of the equation.
-11ln + 4lnx + lnx = -1lnx + lnx

Combine like terms: 4lnx + lnx = 5lnx
-11ln + 5lnx = -1lnx + lnx

Combine like terms: -1lnx + lnx = 0
-11ln + 5lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-11 + 5x) = 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 '(-11 + 5x)' equal to zero and attempt to solve: Simplifying -11 + 5x = 0 Solving -11 + 5x = 0 Move all terms containing l to the left, all other terms to the right. Add '11' to each side of the equation. -11 + 11 + 5x = 0 + 11 Combine like terms: -11 + 11 = 0 0 + 5x = 0 + 11 5x = 0 + 11 Combine like terms: 0 + 11 = 11 5x = 11 Add '-5x' to each side of the equation. 5x + -5x = 11 + -5x Combine like terms: 5x + -5x = 0 0 = 11 + -5x Simplifying 0 = 11 + -5x 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.
