Solution for ln(2x-5)=ln(5)-ln(x-1) equation:


Simplifying
ln(2x + -5) = ln(5) + -1ln(x + -1)

Reorder the terms:
ln(-5 + 2x) = ln(5) + -1ln(x + -1)
(-5 * ln + 2x * ln) = ln(5) + -1ln(x + -1)
(-5ln + 2lnx) = ln(5) + -1ln(x + -1)

Reorder the terms for easier multiplication:
-5ln + 2lnx = 5ln + -1ln(x + -1)

Reorder the terms:
-5ln + 2lnx = 5ln + -1ln(-1 + x)
-5ln + 2lnx = 5ln + (-1 * -1ln + x * -1ln)
-5ln + 2lnx = 5ln + (1ln + -1lnx)

Combine like terms: 5ln + 1ln = 6ln
-5ln + 2lnx = 6ln + -1lnx

Solving
-5ln + 2lnx = 6ln + -1lnx

Solving for variable 'l'.

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

Add '-6ln' to each side of the equation.
-5ln + -6ln + 2lnx = 6ln + -6ln + -1lnx

Combine like terms: -5ln + -6ln = -11ln
-11ln + 2lnx = 6ln + -6ln + -1lnx

Combine like terms: 6ln + -6ln = 0
-11ln + 2lnx = 0 + -1lnx
-11ln + 2lnx = -1lnx

Add 'lnx' to each side of the equation.
-11ln + 2lnx + lnx = -1lnx + lnx

Combine like terms: 2lnx + lnx = 3lnx
-11ln + 3lnx = -1lnx + lnx

Combine like terms: -1lnx + lnx = 0
-11ln + 3lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-11 + 3x) = 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 + 3x)' equal to zero and attempt to solve: Simplifying -11 + 3x = 0 Solving -11 + 3x = 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 + 3x = 0 + 11 Combine like terms: -11 + 11 = 0 0 + 3x = 0 + 11 3x = 0 + 11 Combine like terms: 0 + 11 = 11 3x = 11 Add '-3x' to each side of the equation. 3x + -3x = 11 + -3x Combine like terms: 3x + -3x = 0 0 = 11 + -3x Simplifying 0 = 11 + -3x 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.
